WEBVTT - Marshall Brain's News Roundup: May 6th, 2011

0:00:00.520 --> 0:00:03.600
<v Speaker 1>Welcome to brain Stuff from house stuff works dot com

0:00:03.600 --> 0:00:14.760
<v Speaker 1>where smart happens. Hi. I'm Marshall Brandon. Welcome to this

0:00:14.840 --> 0:00:18.520
<v Speaker 1>week's Friday news round up. Obviously, the big news this

0:00:18.560 --> 0:00:21.880
<v Speaker 1>week has been the assault on Osama bin Laden's compound

0:00:21.920 --> 0:00:25.480
<v Speaker 1>in Pakistan, which was announced early on Monday morning from

0:00:25.480 --> 0:00:29.480
<v Speaker 1>the White House. Two interesting side stories that have captured

0:00:29.520 --> 0:00:33.000
<v Speaker 1>people's attention during the week have been the military group

0:00:33.080 --> 0:00:36.680
<v Speaker 1>that carried out the raid and the helicopter they used

0:00:36.680 --> 0:00:40.599
<v Speaker 1>to do it. The group is called Team six, an

0:00:40.600 --> 0:00:44.919
<v Speaker 1>elite unit of the already elite Navy Seals. You can

0:00:44.960 --> 0:00:48.720
<v Speaker 1>google brain stuff Team six to learn more about them.

0:00:48.760 --> 0:00:51.520
<v Speaker 1>It's a pretty interesting group. There's even a Team six

0:00:51.680 --> 0:00:55.320
<v Speaker 1>dog that wears body armor, a camera, and is able

0:00:55.360 --> 0:00:58.720
<v Speaker 1>to parachute from fifty feet like the rest of the team.

0:00:58.760 --> 0:01:02.560
<v Speaker 1>The existence of Team six wasn't that surprising, because we

0:01:02.600 --> 0:01:05.400
<v Speaker 1>know that the U. S. Government has lots of secret teams,

0:01:05.640 --> 0:01:08.040
<v Speaker 1>and if Team six is now known to the public,

0:01:08.080 --> 0:01:11.280
<v Speaker 1>we can be sure that there's a Team seven, eight, nine, whatever,

0:01:11.720 --> 0:01:15.720
<v Speaker 1>and we'll never hear about those. But the stealth helicopter

0:01:15.880 --> 0:01:20.920
<v Speaker 1>was the unexpected thing. Apparently the military has created helicopters

0:01:20.959 --> 0:01:24.760
<v Speaker 1>that are quiet and radar evading. According to one article,

0:01:24.840 --> 0:01:28.360
<v Speaker 1>the radar evading part comes from the use of technology

0:01:28.520 --> 0:01:32.120
<v Speaker 1>like that found in the original F one seventeen. The

0:01:32.200 --> 0:01:35.560
<v Speaker 1>F one seventeen was the first stealth fighter, and if

0:01:35.600 --> 0:01:38.800
<v Speaker 1>you ever saw it, it really surprised you. Instead of

0:01:38.800 --> 0:01:42.280
<v Speaker 1>being curvy and streamlined like a normal airplane, the F

0:01:42.520 --> 0:01:47.160
<v Speaker 1>one seventeen was completely angular. Every surface of it was

0:01:47.200 --> 0:01:51.120
<v Speaker 1>a flat plane. The idea was that when radio waves

0:01:51.200 --> 0:01:54.400
<v Speaker 1>from a radar unit hit the F one seventeen, they

0:01:54.440 --> 0:01:57.800
<v Speaker 1>would reflect off of the flat planes of the airplane

0:01:58.120 --> 0:02:01.880
<v Speaker 1>at an angle, rather than reflecting back to the radar unit,

0:02:01.920 --> 0:02:05.040
<v Speaker 1>so that the radar unit could sense the plane. As

0:02:05.080 --> 0:02:08.360
<v Speaker 1>far as the radar unit was concerned, the plane was

0:02:08.440 --> 0:02:12.519
<v Speaker 1>completely invisible and less. One of the flat planes happened

0:02:12.560 --> 0:02:15.560
<v Speaker 1>to be angled just right so it faced towards the

0:02:15.680 --> 0:02:19.040
<v Speaker 1>radar unit, and then you'd get a flash from the airplane,

0:02:19.240 --> 0:02:22.320
<v Speaker 1>but that was a really rare event. The Team Sex

0:02:22.440 --> 0:02:27.000
<v Speaker 1>helicopter apparently used this technique as well, along with quieting

0:02:27.040 --> 0:02:29.600
<v Speaker 1>technology to cut the noise from the engines and the

0:02:29.680 --> 0:02:33.240
<v Speaker 1>rotors of the helicopter. The fact that the helicopter crashed

0:02:33.320 --> 0:02:36.959
<v Speaker 1>during the mission was most unfortunate. Just imagine if they

0:02:37.080 --> 0:02:40.399
<v Speaker 1>hadn't killed Bin Laden, it would have been a total fiasco.

0:02:40.880 --> 0:02:44.840
<v Speaker 1>You can google brain stuff Stealth Helicopter for more information

0:02:44.840 --> 0:02:48.839
<v Speaker 1>on this machine. So besides the Bin Laden stuff, what

0:02:48.919 --> 0:02:52.040
<v Speaker 1>was the most popular topic this week on brain Stuff?

0:02:52.600 --> 0:02:58.000
<v Speaker 1>One was an article entitled Amazing Examples of Superhuman speed

0:02:58.000 --> 0:03:02.720
<v Speaker 1>and Accuracy. It's a VIDEOEO montage showing people doing things

0:03:02.760 --> 0:03:06.480
<v Speaker 1>that seem impossible, sort of like what Team six was doing.

0:03:07.120 --> 0:03:10.480
<v Speaker 1>One guy, for example, is able to catch arrows as

0:03:10.520 --> 0:03:14.079
<v Speaker 1>they fly by. When you consider that arrows typically fly

0:03:14.200 --> 0:03:16.480
<v Speaker 1>at the speed of more than a hundred feet per second,

0:03:16.560 --> 0:03:20.120
<v Speaker 1>it's a pretty amazing feat. But even more amazing is

0:03:20.200 --> 0:03:24.640
<v Speaker 1>the modern samurai who can slice an air soft pellet

0:03:24.720 --> 0:03:28.400
<v Speaker 1>traveling at two feet per second. An air soft pellet

0:03:28.560 --> 0:03:31.000
<v Speaker 1>is a plastic sphere about the size of a p

0:03:31.720 --> 0:03:34.760
<v Speaker 1>and once it's shot from the gun, there are two problems.

0:03:35.000 --> 0:03:38.000
<v Speaker 1>The first is the reaction time. There just isn't that

0:03:38.080 --> 0:03:41.400
<v Speaker 1>much time to draw the sword and position it. And

0:03:41.440 --> 0:03:44.840
<v Speaker 1>then there's the accuracy part, getting the blade within the

0:03:44.880 --> 0:03:48.320
<v Speaker 1>diameter of the pellet. I would have a problem hitting

0:03:48.360 --> 0:03:50.400
<v Speaker 1>an air soft pellet with a sword, even if the

0:03:50.400 --> 0:03:53.720
<v Speaker 1>pellet was sitting still on a table. If you google

0:03:53.800 --> 0:03:57.600
<v Speaker 1>Brain Stuff Superhuman Examples, you can watch all the videos

0:03:57.600 --> 0:04:01.880
<v Speaker 1>in this series. Another popular topic this week has to

0:04:01.920 --> 0:04:05.000
<v Speaker 1>do with learning to dunk a basketball even if you're

0:04:05.120 --> 0:04:09.160
<v Speaker 1>less than six ft tall. Is this possible? Yes, it is.

0:04:09.400 --> 0:04:11.960
<v Speaker 1>I found one video showing a five ft five inch

0:04:12.040 --> 0:04:15.520
<v Speaker 1>guy dunking a ball, so it's definitely possible. How do

0:04:15.600 --> 0:04:19.279
<v Speaker 1>they do it? The first key is light weight. You

0:04:19.320 --> 0:04:22.159
<v Speaker 1>have to eliminate every bit of fat on your body

0:04:22.200 --> 0:04:25.320
<v Speaker 1>because weight reduces the height of your jump. Then you

0:04:25.400 --> 0:04:29.480
<v Speaker 1>need to do weight training and exercises to develop explosive

0:04:29.520 --> 0:04:32.000
<v Speaker 1>power in your legs, and then you need to practice

0:04:32.040 --> 0:04:34.400
<v Speaker 1>to get the techniques down. If you want to learn

0:04:34.440 --> 0:04:39.440
<v Speaker 1>to dunk, google martial Brain Dunk for details. Why do

0:04:39.600 --> 0:04:43.520
<v Speaker 1>human beings have the power to reason? There's an article

0:04:43.560 --> 0:04:47.360
<v Speaker 1>in Interesting Reading seven forty five that is just fascinating.

0:04:47.720 --> 0:04:51.039
<v Speaker 1>It's talking about a very peculiar trap that the human

0:04:51.080 --> 0:04:56.359
<v Speaker 1>mind falls into called confirmation bias. Confirmation biases the source

0:04:56.480 --> 0:05:01.000
<v Speaker 1>of all manner of superstition and human culture. The superstition

0:05:01.120 --> 0:05:03.760
<v Speaker 1>discussed in the article has to do with the perception

0:05:03.880 --> 0:05:08.039
<v Speaker 1>of NBA players and fans. Here's basketball again, that a

0:05:08.120 --> 0:05:12.960
<v Speaker 1>player can have a shooting streak. When players statistics are analyzed,

0:05:13.040 --> 0:05:17.080
<v Speaker 1>there's no statistical evidence whatsoever to support the idea of

0:05:17.080 --> 0:05:21.279
<v Speaker 1>a shooting streak. The belief in streaks is pure superstition.

0:05:21.680 --> 0:05:25.440
<v Speaker 1>But of fans and players believe in the idea of

0:05:25.520 --> 0:05:29.520
<v Speaker 1>shooting streaks nonetheless. So the article asks why would our

0:05:29.560 --> 0:05:33.440
<v Speaker 1>brains evolve in a way that promotes confirmation bias given

0:05:33.520 --> 0:05:37.200
<v Speaker 1>that it's always wrong. Let me quote one little paragraph

0:05:37.200 --> 0:05:40.239
<v Speaker 1>from the article. Quote, But if you take the point

0:05:40.240 --> 0:05:44.440
<v Speaker 1>of view of the argumentative theory, having a confirmation bias

0:05:44.560 --> 0:05:48.520
<v Speaker 1>makes complete sense. When you're trying to convince someone, you

0:05:48.640 --> 0:05:51.400
<v Speaker 1>don't want to find arguments for the other side. You

0:05:51.440 --> 0:05:54.279
<v Speaker 1>want to find arguments for your side, and that's what

0:05:54.400 --> 0:05:58.880
<v Speaker 1>the confirmation bias helps you to do. End quote. Yikes,

0:05:59.640 --> 0:06:01.680
<v Speaker 1>I mean, what else can you say to that. It's like,

0:06:01.720 --> 0:06:04.880
<v Speaker 1>we have something built into our brains that causes us

0:06:04.920 --> 0:06:08.160
<v Speaker 1>to perceive the world incorrectly, and we do it so

0:06:08.200 --> 0:06:10.960
<v Speaker 1>that we can have arguments with other people. Anyway, it

0:06:11.000 --> 0:06:13.960
<v Speaker 1>helps to us understand a little more about how human

0:06:14.000 --> 0:06:17.880
<v Speaker 1>beings function. If you google Interesting Reading number seven forty five,

0:06:17.920 --> 0:06:21.640
<v Speaker 1>you can get the details. Also in Interesting Reading number

0:06:21.720 --> 0:06:25.039
<v Speaker 1>seven forty five is a fascinating article that interviews a

0:06:25.160 --> 0:06:29.040
<v Speaker 1>car salesman to better understand how consumers can deal with them.

0:06:29.440 --> 0:06:32.480
<v Speaker 1>One of the questions he's asked is what's the best

0:06:32.480 --> 0:06:35.839
<v Speaker 1>way to get a good deal. The answer is, quote,

0:06:36.200 --> 0:06:40.760
<v Speaker 1>the best deals are really situational end quote. In other words,

0:06:40.839 --> 0:06:43.680
<v Speaker 1>on any given car lot, there is a car, or

0:06:43.760 --> 0:06:46.800
<v Speaker 1>there are several cars that have been sitting there for

0:06:46.839 --> 0:06:49.960
<v Speaker 1>a long time. It could be something as silly as

0:06:50.040 --> 0:06:53.080
<v Speaker 1>the color that's causing the problem. People just won't buy

0:06:53.120 --> 0:06:56.080
<v Speaker 1>the car because of the color. If you aren't picky,

0:06:56.200 --> 0:06:59.599
<v Speaker 1>then finding those cars may get you the best deal.

0:07:00.160 --> 0:07:02.560
<v Speaker 1>There are lots of other good questions in the article,

0:07:02.920 --> 0:07:06.160
<v Speaker 1>for example, when is the best time to buy a car?

0:07:06.720 --> 0:07:10.120
<v Speaker 1>Or what is it with dealer add ons? What can

0:07:10.160 --> 0:07:12.960
<v Speaker 1>you do to avoid them? Or how much profit is

0:07:13.040 --> 0:07:15.920
<v Speaker 1>in each car? Things like that. If you google Interesting

0:07:15.920 --> 0:07:18.680
<v Speaker 1>Reading number seven forty five you can read more from

0:07:18.720 --> 0:07:23.440
<v Speaker 1>this car salesman. Think about your local blood bank. The

0:07:23.560 --> 0:07:27.720
<v Speaker 1>blood in it has to come from generous human beings

0:07:27.760 --> 0:07:31.120
<v Speaker 1>making donations, and it has to be the right type

0:07:31.160 --> 0:07:34.800
<v Speaker 1>for the recipient, and it has a short shelf life.

0:07:35.320 --> 0:07:38.679
<v Speaker 1>This is not a great product to have laying around

0:07:38.680 --> 0:07:42.880
<v Speaker 1>on shelves. What if scientists could come up with synthetic blood,

0:07:42.920 --> 0:07:46.040
<v Speaker 1>a much better product that could be made in a factory,

0:07:46.480 --> 0:07:50.520
<v Speaker 1>doesn't care about blood types and lasts for years. Such

0:07:50.560 --> 0:07:54.040
<v Speaker 1>a synthetic apparently save the life of a woman recently.

0:07:54.520 --> 0:07:57.120
<v Speaker 1>It's still experimental. It has a long way to go

0:07:57.200 --> 0:07:59.680
<v Speaker 1>to get full approval, but it does show a lot

0:07:59.720 --> 0:08:03.000
<v Speaker 1>of promise. If you google interesting Reading number seven forty five,

0:08:03.080 --> 0:08:05.679
<v Speaker 1>you can learn more about the woman who was saved

0:08:05.720 --> 0:08:09.400
<v Speaker 1>and the blood that saved her. Is the sodium in

0:08:09.480 --> 0:08:12.920
<v Speaker 1>table salt really bad for you? We've all been educated

0:08:12.960 --> 0:08:15.960
<v Speaker 1>to think so, and there's huge momentum in the marketplace

0:08:16.040 --> 0:08:18.920
<v Speaker 1>right now to suck salt out of processed foods and

0:08:18.960 --> 0:08:23.600
<v Speaker 1>restaurant foods. But a new study is challenging the idea. Apparently,

0:08:23.720 --> 0:08:28.440
<v Speaker 1>in some populations, lowered sodium intake actually creates more problems

0:08:28.440 --> 0:08:31.400
<v Speaker 1>than it solves. The study was published in the Journal

0:08:31.440 --> 0:08:35.040
<v Speaker 1>of the American Medical Association, a reputable source, but it

0:08:35.120 --> 0:08:38.079
<v Speaker 1>flies in the face of all prior research, so it's

0:08:38.120 --> 0:08:41.200
<v Speaker 1>suspect at the moment. If you google Interesting Reading seven

0:08:41.280 --> 0:08:44.640
<v Speaker 1>forty four, you can learn more about this study and

0:08:44.720 --> 0:08:48.760
<v Speaker 1>what it might mean. How might we go about detecting

0:08:48.960 --> 0:08:53.560
<v Speaker 1>highly advanced civilizations of alien beings living elsewhere in our

0:08:53.600 --> 0:08:57.480
<v Speaker 1>galaxy or in the universe. The SETI Project, which recently

0:08:57.559 --> 0:09:01.679
<v Speaker 1>ran out of money, hasn't detected any alien signals for decades,

0:09:02.080 --> 0:09:04.720
<v Speaker 1>so perhaps we need to try a different approach. What

0:09:04.840 --> 0:09:08.559
<v Speaker 1>about looking for artifacts of alien life? For example, one

0:09:08.640 --> 0:09:13.480
<v Speaker 1>article discusses super advanced alien cultures and how they might

0:09:13.559 --> 0:09:17.480
<v Speaker 1>try tapping into the energy resources of a black hole.

0:09:18.000 --> 0:09:20.480
<v Speaker 1>In fact, they might try to create their own black

0:09:20.520 --> 0:09:23.360
<v Speaker 1>holes for energy, and one way to look for artificially

0:09:23.400 --> 0:09:26.600
<v Speaker 1>created black holes would be to look for black holes

0:09:26.640 --> 0:09:30.240
<v Speaker 1>with a low mass. Natural black holes have a minimum

0:09:30.280 --> 0:09:35.240
<v Speaker 1>mass because they're only formed in certain situations involving star death,

0:09:35.520 --> 0:09:38.880
<v Speaker 1>and artificial black hole might, in theory, be lighter than

0:09:38.920 --> 0:09:42.200
<v Speaker 1>a natural black hole, and since it's lighter, it might

0:09:42.240 --> 0:09:45.640
<v Speaker 1>be detectable. It could be that thinking like this could

0:09:45.760 --> 0:09:49.880
<v Speaker 1>lead us to advanced civilizations. If you google interesting Reading

0:09:49.960 --> 0:09:52.959
<v Speaker 1>number seven forty four, you can learn more about the technique.

0:09:53.640 --> 0:09:56.559
<v Speaker 1>Are you getting the right amount of sleep? And if not,

0:09:56.880 --> 0:09:59.960
<v Speaker 1>is it hurting you? Apparently sleep has a big effe

0:10:00.000 --> 0:10:03.800
<v Speaker 1>act on brain function. According to one article quote around

0:10:03.920 --> 0:10:07.280
<v Speaker 1>seven hours of good quality sleep is fundamental to human

0:10:07.320 --> 0:10:11.080
<v Speaker 1>functioning and well being. End quote. People who get seven

0:10:11.120 --> 0:10:14.600
<v Speaker 1>hours of sleep do the best on cognitive tests. Anywhere

0:10:14.640 --> 0:10:16.800
<v Speaker 1>in the range of six to eight hours of sleep

0:10:16.840 --> 0:10:19.680
<v Speaker 1>seems to be fine. If you get less than that,

0:10:19.840 --> 0:10:22.360
<v Speaker 1>it can cause damage, and if you get more than that,

0:10:22.480 --> 0:10:25.240
<v Speaker 1>it can cause damage. As we get more and more

0:10:25.280 --> 0:10:28.520
<v Speaker 1>connected to the internet, however, sleep seems to take a

0:10:28.520 --> 0:10:31.520
<v Speaker 1>back seat, and that can cause cognitive problems. If you

0:10:31.520 --> 0:10:35.120
<v Speaker 1>google interesting Reading number seven forty three, you can learn

0:10:35.160 --> 0:10:38.280
<v Speaker 1>more about sleep patterns and the amount of sleep you

0:10:38.280 --> 0:10:41.600
<v Speaker 1>should be getting at night. What do you think is

0:10:41.679 --> 0:10:45.720
<v Speaker 1>the most popular form of cosmetic surgery in the United States?

0:10:46.160 --> 0:10:48.920
<v Speaker 1>Is it breast implants? Is it know his jobs as

0:10:49.000 --> 0:10:53.199
<v Speaker 1>it tummy tuchs? No, it's LiPo suction NG with close

0:10:53.280 --> 0:10:56.920
<v Speaker 1>to half a million LiPo section events per year. So

0:10:57.000 --> 0:11:01.120
<v Speaker 1>let's say you go have liposuction. You might have some

0:11:01.200 --> 0:11:04.000
<v Speaker 1>fat sucked out of your thighs or your stomach. What

0:11:04.320 --> 0:11:08.760
<v Speaker 1>happens next, Basically a year later, the fat comes back

0:11:08.800 --> 0:11:11.160
<v Speaker 1>for most people, but it doesn't come back in the

0:11:11.240 --> 0:11:14.600
<v Speaker 1>same place because there are now less fat cells there

0:11:14.640 --> 0:11:17.480
<v Speaker 1>and there's probably been damage around that area. As far

0:11:17.480 --> 0:11:21.280
<v Speaker 1>as fat cells are concerned. Instead, it comes back somewhere else.

0:11:21.720 --> 0:11:25.079
<v Speaker 1>Often it comes back in the arms. But even so

0:11:25.480 --> 0:11:28.640
<v Speaker 1>people can still be happy with the results of liposection.

0:11:28.760 --> 0:11:31.960
<v Speaker 1>The article puts it this way. Quote. Nonetheless, the women

0:11:31.960 --> 0:11:35.439
<v Speaker 1>in the study who had liposection were happy. Dr Eco

0:11:35.559 --> 0:11:39.040
<v Speaker 1>said they had hated their hips and thighs and just

0:11:39.200 --> 0:11:42.720
<v Speaker 1>wanted that fat gone. End quote. Apparently it doesn't matter

0:11:42.760 --> 0:11:44.920
<v Speaker 1>if the arms get heavier in that case. If you

0:11:44.960 --> 0:11:47.920
<v Speaker 1>google interesting Reading number seven forty two, you can learn

0:11:47.920 --> 0:11:51.160
<v Speaker 1>more about the procedure and how it affects your body afterwards.

0:11:52.240 --> 0:11:55.160
<v Speaker 1>For some time, scientists have been able to create and

0:11:55.240 --> 0:11:59.680
<v Speaker 1>capture antimatter, but mostly it's been anti electrons, also known

0:11:59.720 --> 0:12:04.520
<v Speaker 1>as hasitrons because they're created both naturally and artificially. Within

0:12:04.559 --> 0:12:09.079
<v Speaker 1>the last decade, scientists have created anti hydrogen by combining

0:12:09.200 --> 0:12:13.319
<v Speaker 1>anti protons with anti electrons, but storage times have been

0:12:13.480 --> 0:12:17.319
<v Speaker 1>very short, typically less than a second. Now, scientists at

0:12:17.400 --> 0:12:21.120
<v Speaker 1>CERN have created more than three hundred anti hydrogen atoms

0:12:21.120 --> 0:12:24.400
<v Speaker 1>at one time, and they've kept them alive for fifteen minutes.

0:12:24.920 --> 0:12:28.160
<v Speaker 1>Why are they doing this? One reason, obviously, is because

0:12:28.200 --> 0:12:31.079
<v Speaker 1>the warp drive in Star Trek is powered by antimatter,

0:12:31.200 --> 0:12:35.920
<v Speaker 1>making antimatter intrinsically cool. The other reason, though, is because

0:12:36.040 --> 0:12:40.640
<v Speaker 1>there's this huge unanswered question does the gravity created by

0:12:40.760 --> 0:12:45.320
<v Speaker 1>matter attract or repel antimatter? As amazing as it sounds,

0:12:45.360 --> 0:12:48.160
<v Speaker 1>we do not actually know which it is, but we

0:12:48.200 --> 0:12:50.880
<v Speaker 1>are about to find out. If you google Interesting Reading

0:12:50.920 --> 0:12:54.480
<v Speaker 1>number seven forty two you can get the details. And finally,

0:12:54.760 --> 0:12:57.640
<v Speaker 1>did you know that it's illegal for a company to

0:12:57.800 --> 0:13:02.400
<v Speaker 1>leave a prerecorded message on your cell phones voicemail? Apparently

0:13:02.400 --> 0:13:05.040
<v Speaker 1>it is. An article this week reports that a guy

0:13:05.200 --> 0:13:08.280
<v Speaker 1>was getting a lot of harassing calls from debt collection

0:13:08.320 --> 0:13:12.400
<v Speaker 1>agencies and these calls were invalid, and he managed to

0:13:12.679 --> 0:13:16.920
<v Speaker 1>sue the offending companies. According to the article, quote to

0:13:16.960 --> 0:13:20.520
<v Speaker 1>make a long story short, so far, I have successfully

0:13:20.600 --> 0:13:23.640
<v Speaker 1>sued three of these collection companies and settled for more

0:13:23.679 --> 0:13:26.600
<v Speaker 1>than five thousand dollars out of court. All it cost

0:13:26.679 --> 0:13:29.720
<v Speaker 1>me was thirty five dollars and twenty minutes per suit.

0:13:30.240 --> 0:13:33.840
<v Speaker 1>End quote. It's nice when good triumphs over evil. You

0:13:37.080 --> 0:13:41.320
