0:02 when you feel good your brain is
0:04 releasing one of the happy chemicals
0:08 dopamine serotonin oxytocin or endorphin
0:11 we want these good feelings all the time
0:13 but they are not meant to be on for no
0:16 reason they're designed to reward you
0:18 with a good feeling when you do
0:20 something good for your survival our
0:23 brain defines survival in a quirky way
0:26 alas which is why we all do quirky
0:30 things to feel good our happy chemicals
0:32 are inherited from earlier mammals and
0:35 we control them with brain structures
0:38 that all mammals have in common the
0:41 mammal brain can't tell you in words why
0:44 it turns on the chemicals because it
0:48 doesn't process language when you know
0:51 what turns them on in animals everything
0:54 makes sense dopamine surges in a monkey
0:56 when it sees a fruit it can reach each
0:59 step closer to a reward stimulates more
1:02 dopamine but the joy and excitement of
1:04 dopamine stops when you get what you see
1:07 because it has already done its job then
1:09 you have to do more to get more the
1:12 dopamine spurts of your youth built
1:15 neural pathways that tell you how to
1:19 turn it on today these pathways helped
1:22 our ancestors survive in a harsh world
1:25 and today they help you find rewards in
1:29 ways that work for you before you can
1:31 build new dopamine pathways to turn it
1:34 on in new ways but it takes a lot of
1:37 repetition serotonin oxytocin and
1:41 endorphin have their own jobs to do each
1:44 surge builds the neural pathway that
1:46 tells you to expect more good feelings
1:49 in the same way each spurt is so short
1:52 that you always have to do more to get
1:55 more our brain evolved to promote
1:58 survival not to make you feel good
2:00 nothing is wrong with you you're happy
2:03 chemicals are not designed to be on all
2:06 the time ups and downs are natural but
2:09 you can build new pathways to enjoy more
2:12 happy chemicals in new and healthy
2:14 waise find out all about it at the inner
2:17 mammal Institute we have plenty of free
2:19 resources to help you make peace with
