0:00:11.752,0:00:14.779
The cell phone has greatly [br]changed our lives.

0:00:14.779,0:00:17.780
In many ways,[br]it's more practical.

0:00:17.780,0:00:19.523
We can talk[br]to almost anybody

0:00:19.523,0:00:21.536
from almost anywhere.

0:00:21.536,0:00:23.033
But there's also ways

0:00:23.033,0:00:24.517
that the cell phone[br]has impacted lives

0:00:24.517,0:00:26.263
that you maybe[br]not aware of.

0:00:26.263,0:00:27.282
You see,

0:00:27.282,0:00:29.531
our brain has a natural [br]chemical response

0:00:29.531,0:00:30.747
to the cell phone.

0:00:30.747,0:00:31.767
It's a release

0:00:31.767,0:00:34.267
of the chemical in the brain[br]called dopamine.

0:00:34.267,0:00:35.791
Now, I know it's[br]the dopamine

0:00:35.791,0:00:37.950
is the chemical [br]that makes you feel good.

0:00:37.950,0:00:39.753
But that's not [br]actually the case.

0:00:39.903,0:00:40.962
Dopamine,

0:00:40.962,0:00:43.747
is the chemical that's [br]responsible for our seeking.

0:00:43.747,0:00:45.027
So we look [br]for something,

0:00:45.027,0:00:46.096
and we find it,

0:00:46.096,0:00:47.529
and we get [br]a dopamine release.

0:00:47.529,0:00:49.044
And we look for[br]something else,

0:00:49.044,0:00:50.784
we get another[br]dopamine release.

0:00:50.784,0:00:52.229
This is [br]what's known as,

0:00:52.229,0:00:54.246
again, the dopamine loop.

0:00:54.246,0:00:55.792
This is the same[br]thing that occurs

0:00:55.792,0:00:58.264
when you get on the internet[br]and you're doing a search,

0:00:58.264,0:01:00.234
say, for a recipe for dinner.

0:01:00.234,0:01:02.218
And you find yourself, [br]an hour later,

0:01:02.218,0:01:04.103
light years away [br]from where you started.

0:01:04.103,0:01:06.237
Now you're reading[br]about designer breed dogs

0:01:06.237,0:01:08.520
(Laughter)

0:01:08.520,0:01:10.277
and dinner[br]still isn't ready.

0:01:10.277,0:01:12.502
(Laughter)

0:01:13.512,0:01:16.026
The cell phone has greatly [br]impacted our lives,

0:01:16.026,0:01:20.522
and - in some ways [br]we become dependent again.

0:01:20.522,0:01:22.770
Here's my story.

0:01:22.770,0:01:25.514
I had the original cell phone [br]that came with my plan.

0:01:25.514,0:01:28.239
It wasn't fancy,[br]no text, no camera,

0:01:28.239,0:01:30.745
but it was practical,[br]and I kept it in my purse

0:01:30.745,0:01:33.750
and I used it[br]when it was necessary.

0:01:33.750,0:01:36.751
Then came the iPhone.[br](Laughter)

0:01:36.751,0:01:39.509
Now I had camera, [br]internet, email,

0:01:39.509,0:01:41.739
and a whole host [br]of phone applications,

0:01:41.739,0:01:44.762
in an all-in-one[br]hand-held unit.

0:01:44.762,0:01:45.771
And I found myself,

0:01:45.771,0:01:48.481
really developing [br]a dependence on this phone.

0:01:48.481,0:01:51.011
I would carry it with me[br]from room to room in the house,

0:01:51.011,0:01:52.521
even taking it [br]in the backyard,

0:01:52.521,0:01:54.513
when I went to garden.

0:01:54.513,0:01:56.041
But my dependence worsened

0:01:56.041,0:01:58.521
when I get into [br]a relationship with a texter.

0:01:58.521,0:01:59.768
I found myself,

0:01:59.768,0:02:01.754
on an emotional [br]roller coaster.

0:02:01.754,0:02:04.069
(Laughter)

0:02:04.069,0:02:05.277
I so looked forward

0:02:05.277,0:02:07.016
to the texts [br]I would get from him,

0:02:07.016,0:02:09.183
and when I got them [br]I be elated and excited,

0:02:09.183,0:02:11.754
but when they didn't come in,[br]I found myself really low.

0:02:11.754,0:02:13.768
(Laughter)

0:02:13.768,0:02:15.503
So this intrigued me.

0:02:15.503,0:02:17.248
And I started looking[br]at how other people

0:02:17.248,0:02:18.763
use their cell phone.

0:02:18.763,0:02:20.229
Families on cell phone.

0:02:20.229,0:02:22.762
Parents talking on the phone [br]instead of to their kids,

0:02:22.762,0:02:24.245
kids on the cell phone.

0:02:24.245,0:02:25.506
I go into restaurants,

0:02:25.506,0:02:28.258
and whole tables,[br]everybody on the cell phone.

0:02:28.258,0:02:29.774
(Laughter)

0:02:29.774,0:02:31.564
So, I decided [br]to do some research.

0:02:32.274,0:02:33.516
It turns out that

0:02:33.516,0:02:35.217
everything about[br]this technology

0:02:35.217,0:02:37.510
is designed to rope us in,

0:02:37.510,0:02:39.241
from the alert that it emits

0:02:39.241,0:02:41.789
to the amount of text [br]you can see on the screen.

0:02:41.789,0:02:43.247
And we buy into it,

0:02:43.247,0:02:45.779
because we become [br]information seekers.

0:02:47.749,0:02:50.241
Even the text [br]on a news media.

0:02:50.241,0:02:51.765
audios, visuals

0:02:51.765,0:02:53.720
and texts scrolling [br]across the screen,

0:02:53.720,0:02:55.270
and we go for it.

0:02:56.750,0:02:58.742
The most common[br]use of cell phones

0:02:58.742,0:03:01.252
is occurring [br]in college students.

0:03:01.252,0:03:04.258
They're receiving[br]about a hundred texts a day,

0:03:04.258,0:03:05.767
and checking for their texts,

0:03:05.767,0:03:08.245
an additional sixty times a day.

0:03:08.245,0:03:09.751
Now, their compulsive addiction

0:03:09.751,0:03:11.781
isn't to the cell phone,

0:03:11.781,0:03:13.515
it's to the dopamine they get

0:03:13.515,0:03:15.079
every time they get a message.

0:03:17.019,0:03:19.511
Think how you feel [br]when you check your messages

0:03:19.511,0:03:20.763
and you don't have any,

0:03:20.763,0:03:22.259
versus when you do.

0:03:22.259,0:03:24.504
Elated, valued, kind of important.

0:03:25.754,0:03:27.232
The cell phones also,

0:03:27.232,0:03:28.761
change the way we think

0:03:28.761,0:03:30.503
and we communicate with people.

0:03:30.503,0:03:32.504
We'd rather communicate [br]in snippets of text,

0:03:32.504,0:03:35.758
rather than way through[br]a voicemail or email message.

0:03:35.758,0:03:37.760
And our focus [br]and our attention span,

0:03:37.760,0:03:38.773
is shorter.

0:03:39.493,0:03:42.051
We split from topic to topic,[br]and idea to idea,

0:03:42.051,0:03:44.223
hardly ever finishing anything.

0:03:44.223,0:03:45.510
And even in the Google age,

0:03:45.510,0:03:47.510
with all this information[br]provided to us,

0:03:47.510,0:03:49.494
we're willing to take [br]the first response supplied,

0:03:49.494,0:03:52.273
rather than [br]really verify it.

0:03:53.753,0:03:55.241
Her's another thing.

0:03:55.751,0:03:57.773
How do you feel [br]when you drive away

0:03:57.773,0:04:00.238
and you realize you've left [br]your cell phone behind?

0:04:00.238,0:04:01.492
(Laughter)

0:04:01.492,0:04:03.244
Do you turn around [br]to go back for it,

0:04:03.244,0:04:04.739
no matter how[br]late you are,

0:04:04.739,0:04:06.250
to wherever [br]you're going?

0:04:06.250,0:04:07.774
(Laughter)

0:04:07.774,0:04:09.051
Well, as it turns out,

0:04:09.051,0:04:12.253
there's been a reported [br]increase in anxiety of this kind,

0:04:12.253,0:04:13.767
and there's [br]a medical condition

0:04:13.767,0:04:15.510
associated with it.

0:04:15.510,0:04:16.789
Nomophobia.[br]

0:04:16.789,0:04:19.252
(Laughter)[br]No, really.

0:04:19.252,0:04:21.257
(Laughter)

0:04:21.507,0:04:23.519
No mobile phone phobia.

0:04:23.519,0:04:25.246
And it's the condition that arises

0:04:25.246,0:04:26.719
from the anxiety [br]that we feel

0:04:26.719,0:04:28.355
when we don't[br]have our cell phone,

0:04:28.355,0:04:30.522
or when you don't [br]have communication.

0:04:31.212,0:04:33.777
So, I want to offer you [br]a challenge today.

0:04:34.227,0:04:35.755
For the next two weeks,

0:04:36.245,0:04:39.770
put your cell phone [br]out of your physical location,

0:04:39.770,0:04:41.508
for an hour a day.

0:04:41.508,0:04:42.775
For one hour a day,

0:04:42.775,0:04:44.251
be without the cell phone.

0:04:44.251,0:04:45.763
Focus on something else.

0:04:45.763,0:04:47.236
Your surroundings,

0:04:47.236,0:04:48.261
the people [br]around you,

0:04:48.261,0:04:49.272
or just gaze into

0:04:49.272,0:04:51.263
these beautiful New Mexico skies.

0:04:52.513,0:04:54.774
One hour a day,[br]dopamine free.

0:04:55.244,0:04:57.788
(Applause)[br]Hello, mum...

0:04:57.788,0:04:59.777
(Applause)
