1
00:00:11,752 --> 00:00:14,779
The cell phone has greatly 
changed our lives.

2
00:00:14,779 --> 00:00:17,780
In many ways,
it's more practical.

3
00:00:17,780 --> 00:00:19,523
We can talk
to almost anybody

4
00:00:19,523 --> 00:00:21,536
from almost anywhere.

5
00:00:21,536 --> 00:00:23,033
But there's also ways

6
00:00:23,033 --> 00:00:24,517
that the cell phone
has impacted lives

7
00:00:24,517 --> 00:00:26,263
that you maybe
not aware of.

8
00:00:26,263 --> 00:00:27,282
You see,

9
00:00:27,282 --> 00:00:29,531
our brain has a natural 
chemical response

10
00:00:29,531 --> 00:00:30,747
to the cell phone.

11
00:00:30,747 --> 00:00:31,767
It's a release

12
00:00:31,767 --> 00:00:34,267
of the chemical in the brain
called dopamine.

13
00:00:34,267 --> 00:00:35,791
Now, I know it's
the dopamine

14
00:00:35,791 --> 00:00:37,950
is the chemical 
that makes you feel good.

15
00:00:37,950 --> 00:00:39,753
But that's not 
actually the case.

16
00:00:39,903 --> 00:00:40,962
Dopamine,

17
00:00:40,962 --> 00:00:43,747
is the chemical that's 
responsible for our seeking.

18
00:00:43,747 --> 00:00:45,027
So we look 
for something,

19
00:00:45,027 --> 00:00:46,096
and we find it,

20
00:00:46,096 --> 00:00:47,529
and we get 
a dopamine release.

21
00:00:47,529 --> 00:00:49,044
And we look for
something else,

22
00:00:49,044 --> 00:00:50,784
we get another
dopamine release.

23
00:00:50,784 --> 00:00:52,229
This is 
what's known as,

24
00:00:52,229 --> 00:00:54,246
again, the dopamine loop.

25
00:00:54,246 --> 00:00:55,792
This is the same
thing that occurs

26
00:00:55,792 --> 00:00:58,264
when you get on the internet
and you're doing a search,

27
00:00:58,264 --> 00:01:00,234
say, for a recipe for dinner.

28
00:01:00,234 --> 00:01:02,218
And you find yourself, 
an hour later,

29
00:01:02,218 --> 00:01:04,103
light years away 
from where you started.

30
00:01:04,103 --> 00:01:06,237
Now you're reading
about designer breed dogs

31
00:01:06,237 --> 00:01:08,520
(Laughter)

32
00:01:08,520 --> 00:01:10,277
and dinner
still isn't ready.

33
00:01:10,277 --> 00:01:12,502
(Laughter)

34
00:01:13,512 --> 00:01:16,026
The cell phone has greatly 
impacted our lives,

35
00:01:16,026 --> 00:01:20,522
and - in some ways 
we become dependent again.

36
00:01:20,522 --> 00:01:22,770
Here's my story.

37
00:01:22,770 --> 00:01:25,514
I had the original cell phone 
that came with my plan.

38
00:01:25,514 --> 00:01:28,239
It wasn't fancy,
no text, no camera,

39
00:01:28,239 --> 00:01:30,745
but it was practical,
and I kept it in my purse

40
00:01:30,745 --> 00:01:33,750
and I used it
when it was necessary.

41
00:01:33,750 --> 00:01:36,751
Then came the iPhone.
(Laughter)

42
00:01:36,751 --> 00:01:39,509
Now I had camera, 
internet, email,

43
00:01:39,509 --> 00:01:41,739
and a whole host 
of phone applications,

44
00:01:41,739 --> 00:01:44,762
in an all-in-one
hand-held unit.

45
00:01:44,762 --> 00:01:45,771
And I found myself,

46
00:01:45,771 --> 00:01:48,481
really developing 
a dependence on this phone.

47
00:01:48,481 --> 00:01:51,011
I would carry it with me
from room to room in the house,

48
00:01:51,011 --> 00:01:52,521
even taking it 
in the backyard,

49
00:01:52,521 --> 00:01:54,513
when I went to garden.

50
00:01:54,513 --> 00:01:56,041
But my dependence worsened

51
00:01:56,041 --> 00:01:58,521
when I get into 
a relationship with a texter.

52
00:01:58,521 --> 00:01:59,768
I found myself,

53
00:01:59,768 --> 00:02:01,754
on an emotional 
roller coaster.

54
00:02:01,754 --> 00:02:04,069
(Laughter)

55
00:02:04,069 --> 00:02:05,277
I so looked forward

56
00:02:05,277 --> 00:02:07,016
to the texts 
I would get from him,

57
00:02:07,016 --> 00:02:09,183
and when I got them 
I be elated and excited,

58
00:02:09,183 --> 00:02:11,754
but when they didn't come in,
I found myself really low.

59
00:02:11,754 --> 00:02:13,768
(Laughter)

60
00:02:13,768 --> 00:02:15,503
So this intrigued me.

61
00:02:15,503 --> 00:02:17,248
And I started looking
at how other people

62
00:02:17,248 --> 00:02:18,763
use their cell phone.

63
00:02:18,763 --> 00:02:20,229
Families on cell phone.

64
00:02:20,229 --> 00:02:22,762
Parents talking on the phone 
instead of to their kids,

65
00:02:22,762 --> 00:02:24,245
kids on the cell phone.

66
00:02:24,245 --> 00:02:25,506
I go into restaurants,

67
00:02:25,506 --> 00:02:28,258
and whole tables,
everybody on the cell phone.

68
00:02:28,258 --> 00:02:29,774
(Laughter)

69
00:02:29,774 --> 00:02:31,564
So, I decided 
to do some research.

70
00:02:32,274 --> 00:02:33,516
It turns out that

71
00:02:33,516 --> 00:02:35,217
everything about
this technology

72
00:02:35,217 --> 00:02:37,510
is designed to rope us in,

73
00:02:37,510 --> 00:02:39,241
from the alert that it emits

74
00:02:39,241 --> 00:02:41,789
to the amount of text 
you can see on the screen.

75
00:02:41,789 --> 00:02:43,247
And we buy into it,

76
00:02:43,247 --> 00:02:45,779
because we become 
information seekers.

77
00:02:47,749 --> 00:02:50,241
Even the text 
on a news media.

78
00:02:50,241 --> 00:02:51,765
audios, visuals

79
00:02:51,765 --> 00:02:53,720
and texts scrolling 
across the screen,

80
00:02:53,720 --> 00:02:55,270
and we go for it.

81
00:02:56,750 --> 00:02:58,742
The most common
use of cell phones

82
00:02:58,742 --> 00:03:01,252
is occurring 
in college students.

83
00:03:01,252 --> 00:03:04,258
They're receiving
about a hundred texts a day,

84
00:03:04,258 --> 00:03:05,767
and checking for their texts,

85
00:03:05,767 --> 00:03:08,245
an additional sixty times a day.

86
00:03:08,245 --> 00:03:09,751
Now, their compulsive addiction

87
00:03:09,751 --> 00:03:11,781
isn't to the cell phone,

88
00:03:11,781 --> 00:03:13,515
it's to the dopamine they get

89
00:03:13,515 --> 00:03:15,079
every time they get a message.

90
00:03:17,019 --> 00:03:19,511
Think how you feel 
when you check your messages

91
00:03:19,511 --> 00:03:20,763
and you don't have any,

92
00:03:20,763 --> 00:03:22,259
versus when you do.

93
00:03:22,259 --> 00:03:24,504
Elated, valued, kind of important.

94
00:03:25,754 --> 00:03:27,232
The cell phones also,

95
00:03:27,232 --> 00:03:28,761
change the way we think

96
00:03:28,761 --> 00:03:30,503
and we communicate with people.

97
00:03:30,503 --> 00:03:32,504
We'd rather communicate 
in snippets of text,

98
00:03:32,504 --> 00:03:35,758
rather than way through
a voicemail or email message.

99
00:03:35,758 --> 00:03:37,760
And our focus 
and our attention span,

100
00:03:37,760 --> 00:03:38,773
is shorter.

101
00:03:39,493 --> 00:03:42,051
We split from topic to topic,
and idea to idea,

102
00:03:42,051 --> 00:03:44,223
hardly ever finishing anything.

103
00:03:44,223 --> 00:03:45,510
And even in the Google age,

104
00:03:45,510 --> 00:03:47,510
with all this information
provided to us,

105
00:03:47,510 --> 00:03:49,494
we're willing to take 
the first response supplied,

106
00:03:49,494 --> 00:03:52,273
rather than 
really verify it.

107
00:03:53,753 --> 00:03:55,241
Her's another thing.

108
00:03:55,751 --> 00:03:57,773
How do you feel 
when you drive away

109
00:03:57,773 --> 00:04:00,238
and you realize you've left 
your cell phone behind?

110
00:04:00,238 --> 00:04:01,492
(Laughter)

111
00:04:01,492 --> 00:04:03,244
Do you turn around 
to go back for it,

112
00:04:03,244 --> 00:04:04,739
no matter how
late you are,

113
00:04:04,739 --> 00:04:06,250
to wherever 
you're going?

114
00:04:06,250 --> 00:04:07,774
(Laughter)

115
00:04:07,774 --> 00:04:09,051
Well, as it turns out,

116
00:04:09,051 --> 00:04:12,253
there's been a reported 
increase in anxiety of this kind,

117
00:04:12,253 --> 00:04:13,767
and there's 
a medical condition

118
00:04:13,767 --> 00:04:15,510
associated with it.

119
00:04:15,510 --> 00:04:16,789
Nomophobia.


120
00:04:16,789 --> 00:04:19,252
(Laughter)
No, really.

121
00:04:19,252 --> 00:04:21,257
(Laughter)

122
00:04:21,507 --> 00:04:23,519
No mobile phone phobia.

123
00:04:23,519 --> 00:04:25,246
And it's the condition that arises

124
00:04:25,246 --> 00:04:26,719
from the anxiety 
that we feel

125
00:04:26,719 --> 00:04:28,355
when we don't
have our cell phone,

126
00:04:28,355 --> 00:04:30,522
or when you don't 
have communication.

127
00:04:31,212 --> 00:04:33,777
So, I want to offer you 
a challenge today.

128
00:04:34,227 --> 00:04:35,755
For the next two weeks,

129
00:04:36,245 --> 00:04:39,770
put your cell phone 
out of your physical location,

130
00:04:39,770 --> 00:04:41,508
for an hour a day.

131
00:04:41,508 --> 00:04:42,775
For one hour a day,

132
00:04:42,775 --> 00:04:44,251
be without the cell phone.

133
00:04:44,251 --> 00:04:45,763
Focus on something else.

134
00:04:45,763 --> 00:04:47,236
Your surroundings,

135
00:04:47,236 --> 00:04:48,261
the people 
around you,

136
00:04:48,261 --> 00:04:49,272
or just gaze into

137
00:04:49,272 --> 00:04:51,263
these beautiful New Mexico skies.

138
00:04:52,513 --> 00:04:54,774
One hour a day,
dopamine free.

139
00:04:55,244 --> 00:04:57,788
(Applause)
Hello, mum...

140
00:04:57,788 --> 00:04:59,777
(Applause)
