Hello and this is the show that helps you navigate the mayhem of the modern world.

Today I'm chatting to TJ Power.

We as humans spend 300,000 years evolving out in nature.

These chemicals during those 300,000 years, like every part of us, were evolving and trying to help us.

Dopamine, for example, if we were out there hunting

and looking for food and building shelter,

it would reward these behaviors and suddenly our dopamine

would go up because those behaviors were vital to surviving.

If you then put a hunter-gatherer in the modern world, like put our ancestors in the modern world and

suddenly they had sugar and phones and sat inside all day and stopped sleeping and became disconnected,

all these chemicals would drop. And that really is where we're at as a society, all of these chemicals would drop and that really is where we're at as a society.

All of these chemicals are low for all of us.

T.J. is a neuroscientist and the co-founder of Neurify. He's basically the brain behind our brains and yes he's a super clever scientist but he's only human too

He's struggled with addictive behaviors himself so he knows firsthand how to spot those more unhelpful habits from hangovers to endless scrolling on our phones.

But he also now knows how to manage them.

The key is to understand the four primary brain chemicals

that influence our feelings and behaviors. We're talking dopamine,

oxytocin, serotonin and endorphins. These are the things he focuses on in his book,

The dose effect, which will come out later this year. You've probably heard of some if not all of those chemicals. I definitely have heard a lot about

dopamine, certainly in relation to phones and scrolling in these little hits we're trying to get all of the time and I guess a little bit about

oxytocin when I was pregnant but I certainly need to learn more about it and I know a teeny bit about serotonin because I'm pretty

sure it relates to sleep and that's something that I can become a bit obsessed by.
