17
00:00:54,520 --> 00:00:57,040
Speaker 1: guys can't see this because this is just an audio podcast.

18
00:00:57,080 --> 00:00:59,960
Speaker 1: But Chuck is blushing with embarrassment. I've never seen Chuck

19
00:01:00,000 --> 00:01:02,640
Speaker 1: blush before. It's okay, Chuck, I won't judge This is

20
00:01:02,640 --> 00:01:04,640
Speaker 1: not a locker room though, so I wasn't prepared for that.

21
00:01:04,720 --> 00:01:07,520
Speaker 1: Handle your business and we'll wait a second. Every show

22
00:01:07,720 --> 00:01:10,760
Speaker 1: everything's good, So check that that actually brings to mind.

23
00:01:11,040 --> 00:01:13,880
Speaker 1: Um an article I wrote, why do people Blush? Did

24
00:01:13,959 --> 00:01:17,440
Speaker 1: you prep for this podcast? Did you read it? I did? Uh?

25
00:01:17,600 --> 00:01:19,200
Speaker 1: It was It was a good one, Josh. I thought

26
00:01:19,240 --> 00:01:22,199
Speaker 1: that it's pretty interesting. Blushing is one of those um

27
00:01:22,360 --> 00:01:25,440
Speaker 1: things that people probably don't think about very often. Everyone blushes,

28
00:01:25,600 --> 00:01:30,400
Speaker 1: and uh, it's exclusive to humans all of no other

29
00:01:30,600 --> 00:01:34,160
Speaker 1: animal on the planet that blushes exactly. But um, we

30
00:01:34,200 --> 00:01:35,960
Speaker 1: don't we we know how we blush, but we don't

31
00:01:36,040 --> 00:01:38,840
Speaker 1: exactly know why we blush. And isn't that weird that

32
00:01:38,840 --> 00:01:42,760
Speaker 1: that something is ubiquitous and seemingly normal is actually abnormal?

33
00:01:43,280 --> 00:01:45,039
Speaker 1: You know? Do you want to tell the folks at

34
00:01:45,040 --> 00:01:48,120
Speaker 1: home how we blush? Uh? Yeah, well it has to

35
00:01:48,160 --> 00:01:51,160
Speaker 1: do with the uh, the old sympathetic system, which is

36
00:01:51,200 --> 00:01:56,640
Speaker 1: also what controls the fight or flight syndrome or not syndrome.

37
00:01:56,680 --> 00:02:00,280
Speaker 1: But yeah, fans of no so the fight or flights bonds.

38
00:02:00,520 --> 00:02:03,600
Speaker 1: I wanted to say that last time to so fans

39
00:02:03,600 --> 00:02:06,680
Speaker 1: of stuff you should know are will probably be familiar

40
00:02:06,760 --> 00:02:10,760
Speaker 1: with our podcasts on hysterical strength, which I know all

41
00:02:10,800 --> 00:02:12,919
Speaker 1: about the fight or flight response. It's the same thing.

42
00:02:13,000 --> 00:02:17,360
Speaker 1: You're your veins and dilate and more blood gets pumping,

43
00:02:17,400 --> 00:02:20,520
Speaker 1: and your your pupils uh get larger, and then all

44
00:02:20,520 --> 00:02:22,040
Speaker 1: of a sudden you find that you might be able

45
00:02:22,080 --> 00:02:25,359
Speaker 1: to throw a lawn more off your granddaughter like Boots

46
00:02:25,400 --> 00:02:28,120
Speaker 1: he did, Hello Boots, Hello Boots. So yeah, and one

47
00:02:28,120 --> 00:02:31,600
Speaker 1: of the other things is that your your blood vessels dilate, right, right,

48
00:02:31,639 --> 00:02:34,400
Speaker 1: which is the case in blushing, right, Except the thing

49
00:02:34,560 --> 00:02:37,960
Speaker 1: is the blood vessels in your cheeks that actually become flushed.

50
00:02:37,960 --> 00:02:42,360
Speaker 1: Our veins um and oddly, veins don't usually respond at

51
00:02:42,360 --> 00:02:45,359
Speaker 1: all to adrenaline, but for some reason, the veins in

52
00:02:45,440 --> 00:02:48,360
Speaker 1: your cheeks too, and those are the only veins in

53
00:02:48,400 --> 00:02:52,280
Speaker 1: your body that flush or dilate when your fight or

54
00:02:52,280 --> 00:02:55,639
Speaker 1: flight response goes off. I mean, what the heck is that? Yeah, well,

55
00:02:55,680 --> 00:02:57,920
Speaker 1: that's kind of weird because I mean it's what everyone

56
00:02:57,960 --> 00:03:00,680
Speaker 1: would see. I mean, if your kneecaps blood, no one

57
00:03:00,720 --> 00:03:04,160
Speaker 1: would ever know if you're embarrassed, So it happens in

58
00:03:04,160 --> 00:03:06,800
Speaker 1: your face for maybe for a reason, maybe not. But

59
00:03:06,840 --> 00:03:09,840
Speaker 1: there are some theories about why we blush like what Well,

60
00:03:09,919 --> 00:03:11,640
Speaker 1: one of them is that it is in fact on

61
00:03:11,680 --> 00:03:14,000
Speaker 1: the face so other people can see it, because it's

62
00:03:14,400 --> 00:03:17,440
Speaker 1: a form of public apology for a faux pa you

63
00:03:17,520 --> 00:03:19,080
Speaker 1: might have had, or if you stuck your foot in

64
00:03:19,120 --> 00:03:22,040
Speaker 1: your mouth. Um, your blushing is a way to kind

65
00:03:22,080 --> 00:03:24,320
Speaker 1: of be contrite and say, you know, I'm embarrassed and

66
00:03:24,360 --> 00:03:26,960
Speaker 1: I'm sorry. I shouldn't have said that without actually saying that.

67
00:03:27,080 --> 00:03:31,320
Speaker 1: So it's like a physical example of your emotional intellect.

68
00:03:31,360 --> 00:03:33,720
Speaker 1: You're saying, I'm aware of this. Don't don't beat me,

69
00:03:34,040 --> 00:03:36,600
Speaker 1: you know, start a fight with me. It's sort of

70
00:03:36,640 --> 00:03:38,800
Speaker 1: like the same thing that happens. Like if your dog

71
00:03:39,520 --> 00:03:41,320
Speaker 1: hikes his leg on your dining room table and you

72
00:03:41,400 --> 00:03:43,040
Speaker 1: walk in the room, it's a very good chance your

73
00:03:43,040 --> 00:03:44,640
Speaker 1: dog might you know, lower his head and kind of

74
00:03:44,640 --> 00:03:46,800
Speaker 1: back out of the room slowly, or roll over and

75
00:03:46,840 --> 00:03:49,120
Speaker 1: show its belly. Yeah, show it's belly. It's a kind

76
00:03:49,120 --> 00:03:51,680
Speaker 1: of a similar thing. I got you, okay, now, Um,

77
00:03:51,800 --> 00:03:54,000
Speaker 1: I don't buy that one. I think it's kind of

78
00:03:54,040 --> 00:03:56,640
Speaker 1: a clumsy theory. It's not my favorite. I've got a

79
00:03:56,680 --> 00:03:58,720
Speaker 1: favorite theory with blushing. You want here it, We'll be

80
00:03:58,800 --> 00:04:00,840
Speaker 1: that way, Josh, I like I'd love to hear yours.

81
00:04:01,120 --> 00:04:04,120
Speaker 1: My favorite is n p A. UM. It's it's this

82
00:04:04,240 --> 00:04:09,840
Speaker 1: obscure uh theory about human personalities, and the theory is

83
00:04:09,880 --> 00:04:13,560
Speaker 1: that all of them are created based on the foundation

84
00:04:13,600 --> 00:04:19,480
Speaker 1: of narcissism, perfectionism, and aggression. Right and um, all personalities

85
00:04:19,480 --> 00:04:22,719
Speaker 1: can be explained through these three um outlooks or views

86
00:04:22,720 --> 00:04:27,239
Speaker 1: of life. UM. The uh there should be a balance

87
00:04:27,279 --> 00:04:29,719
Speaker 1: between the three, and the more balanced it is probably

88
00:04:29,720 --> 00:04:32,400
Speaker 1: the more normal you are. People who have almost just

89
00:04:32,560 --> 00:04:37,560
Speaker 1: one exclusively tend to be schizophrenic that kind of thing. No, no, no, no,

90
00:04:38,000 --> 00:04:40,719
Speaker 1: well you know, so with m p A or under

91
00:04:40,760 --> 00:04:44,359
Speaker 1: the mp A theory, blushing is actually am It is

92
00:04:44,360 --> 00:04:47,760
Speaker 1: a fight or flight response, but you're actually becoming enraged.

93
00:04:47,800 --> 00:04:51,440
Speaker 1: You're not embarrassed, your your narcissism has been affronted, right,

94
00:04:51,440 --> 00:04:53,440
Speaker 1: I gotta tell you, is the narcissist the mp A

95
00:04:53,560 --> 00:04:55,560
Speaker 1: theory really makes sense to me? Yeah, I felt that

96
00:04:55,600 --> 00:04:57,920
Speaker 1: way before too. I think the rage a little less

97
00:04:58,040 --> 00:05:00,760
Speaker 1: or sorry, a little more than the embarrassment, right Yeah, So,

98
00:05:00,800 --> 00:05:04,039
Speaker 1: I mean maybe we're just confusing it. Who knows. I mean, really,

99
00:05:04,080 --> 00:05:06,200
Speaker 1: at this point, as far as we know about blushing,

100
00:05:06,320 --> 00:05:08,040
Speaker 1: you or I could come up with a pretty adequate

101
00:05:08,080 --> 00:05:11,000
Speaker 1: theory for it, right. Maybe we'll publish one soon, maybe so.

102
00:05:11,040 --> 00:05:12,880
Speaker 1: But the fact is we all blush. There's no denying

103
00:05:12,920 --> 00:05:15,200
Speaker 1: that exactly. Now. You can learn more about it on

Speaker 1: like say, what's the best site to buy a new

110
00:05:31,000 --> 00:05:33,599
Speaker 1: leather jacket? But whether to buy the three or six

111
00:05:33,680 --> 00:05:36,880
Speaker 1: metapixel camera? But thankfully we don't need to think about

112
00:05:36,920 --> 00:05:40,440
Speaker 1: online fraud because for every purchase you make, Visa keeps
