a lot of people have heard about

0:00:03.600,0:00:07.040
dopamine

0:00:04.319,0:00:07.839
as the pleasure molecule and that's one

0:00:07.040,0:00:10.719
thing it does

0:00:07.839,0:00:11.840
dopamine was originally made to make us

0:00:10.719,0:00:13.440
desire

0:00:11.840,0:00:15.839
things that will benefit us

0:00:13.440,0:00:16.480
evolutionarily and reward us when we do

0:00:15.839,0:00:18.720
it so

0:00:16.480,0:00:19.840
eat when you're hungry drink when you're

0:00:18.720,0:00:22.720
thirsty

0:00:19.840,0:00:24.400
reproduction winning competitions these

0:00:22.720,0:00:27.519
are natural things

0:00:24.400,0:00:30.320
your brain develops priorities

0:00:27.519,0:00:31.279
in large part based on how much dopamine

0:00:30.320,0:00:33.520
it's gonna get

0:00:31.279,0:00:35.520
what do you want a hundred dollars or

0:00:33.520,0:00:36.960
what's behind door number two

0:00:35.520,0:00:38.719
there's a good chance what behind door

0:00:36.960,0:00:40.399
number two is like a car or something

0:00:38.719,0:00:42.320
right so they always pick door number

0:00:40.399,0:00:44.960
two that's gonna give you

0:00:42.320,0:00:46.239
more dopamine dopamine doesn't give us

0:00:44.960,0:00:49.760
pleasure for things we

0:00:46.239,0:00:53.120
have it can only make us want more

0:00:49.760,0:00:56.079
once you get it dopamine shuts off

0:00:53.120,0:00:57.120
social media gets you addicted by always

0:00:56.079,0:00:59.600
promising you

0:00:57.120,0:01:01.120
more there's always this sense if i'm

0:00:59.600,0:01:03.120
not on social media

0:01:01.120,0:01:05.519
i'm going to miss out on something i

0:01:03.120,0:01:09.200
need to get more clicks i need to get

0:01:05.519,0:01:11.200
more likes i need to get more friends

0:01:09.200,0:01:12.880
have you ever been kind of scrolling

0:01:11.200,0:01:14.400
through your social media

0:01:12.880,0:01:16.960
looking at these different stories

0:01:14.400,0:01:19.600
looking at these different posts

0:01:16.960,0:01:22.080
and you realize i'm miserable i should

0:01:19.600,0:01:25.040
be doing something else this is boring

0:01:22.080,0:01:26.080
this is making me sad but you can't stop

0:01:25.040,0:01:28.240
because what you're afraid

0:01:26.080,0:01:30.079
of is that there's something down there

0:01:28.240,0:01:31.600
that might be important

0:01:30.079,0:01:33.680
there's something down there that might

0:01:31.600,0:01:34.320
give you more might make your life

0:01:33.680,0:01:36.400
better

0:01:34.320,0:01:37.360
and so you just can't stop and that's

0:01:36.400,0:01:38.640
dopamine

0:01:37.360,0:01:40.720
what's the worst thing that could happen

0:01:38.640,0:01:42.159
with this the danger is that it's no

0:01:40.720,0:01:45.040
longer a tool

0:01:42.159,0:01:45.920
to make your life better it becomes a

0:01:45.040,0:01:48.640
sink

0:01:45.920,0:01:49.360
where it absorbs all of your time all of

0:01:48.640,0:01:51.439
your focus

0:01:49.360,0:01:53.040
all of your energy and everything else

0:01:51.439,0:01:54.799
around it shrivels

0:01:53.040,0:01:56.159
so you stop paying attention to the

0:01:54.799,0:01:57.840
people in your life because all you're

0:01:56.159,0:01:58.880
worried about is getting more dopamine

0:01:57.840,0:02:01.360
off of social media

0:01:58.880,0:02:02.000
that's right what are the consequences

0:02:01.360,0:02:05.520
of us

0:02:02.000,0:02:09.280
being addicted to social media instagram

0:02:05.520,0:02:11.280
twitter texting snap what is the worst

0:02:09.280,0:02:12.640
long-term consequences we could face

0:02:11.280,0:02:14.560
with this well

0:02:12.640,0:02:15.760
how about the end of the human race you

0:02:14.560,0:02:18.800
think so yes

0:02:15.760,0:02:21.200
tell me why we've got so much amazing

0:02:18.800,0:02:22.239
cool stuff we've got all kinds of things

0:02:21.200,0:02:23.920
we can buy

0:02:22.239,0:02:25.680
we've got all kinds of things we can

0:02:23.920,0:02:28.080
experience

0:02:25.680,0:02:30.800
something's got to give what is it that

0:02:28.080,0:02:34.239
we're giving up for all of these things

0:02:30.800,0:02:36.400
the answer is children once an economy

0:02:34.239,0:02:38.560
reaches a certain point of prosperity

0:02:36.400,0:02:40.640
the members of that economy lose

0:02:38.560,0:02:42.959
interest in reproducing

0:02:40.640,0:02:45.360
all of the developed nations have a

0:02:42.959,0:02:47.760
negative population growth rate

0:02:45.360,0:02:49.440
in order to keep the human race going

0:02:47.760,0:02:52.720
each woman needs to have

0:02:49.440,0:02:55.440
2.1 children two children to

0:02:52.720,0:02:56.160
replace her and the father and one to

0:02:55.440,0:02:58.400
replace

0:02:56.160,0:03:00.159
people who die before they have a chance

0:02:58.400,0:03:01.920
to reproduce

0:03:00.159,0:03:04.720
in all developed countries the birth

0:03:01.920,0:03:07.040
rate is less than 2.1 percent

0:03:04.720,0:03:08.319
even in developing nations uh we're

0:03:07.040,0:03:10.800
seeing this happen

0:03:08.319,0:03:12.560
uh it's falling and falling and falling

0:03:10.800,0:03:14.080
we don't have a solution there are some

0:03:12.560,0:03:14.720
countries where they're not paying

0:03:14.080,0:03:17.120
people

0:03:14.720,0:03:18.720
to have children and even that's not

0:03:17.120,0:03:21.760
working as we get

0:03:18.720,0:03:22.640
more and more gadgets that attract our

0:03:21.760,0:03:26.159
attention

0:03:22.640,0:03:28.239
they become substitutes for family

0:03:26.159,0:03:29.760
and ultimately the human race is simply

0:03:28.239,0:03:32.239
going to collapse unless something

0:03:29.760,0:03:32.239
changes
