Gambling (stock trading), fishing, hiking (outings), long-distance running (even marathons), sunbathing

The arrival of spring, hunting, traveling, shopping, strolling in green parks for half an hour every day while eating candy, smoking, watching videos or NSFW images, listening to music

Socializing, partying, bonfire parties, having sex with different people

Why do these things make us happy?

Just compare them to what our ancestors did during the hunter-gatherer stage,

what made them happy,

and you'll understand.

Humans have existed for 3 million years, Homo sapiens for less than 500,000 years. For the vast majority of that time, we were hunter-gatherers, spreading across the globe like the deadliest virus or a swarm of locusts, driving most of Earth's large animals to extinction.

Farming only became widespread 10,000 years ago, industrialization 200 years ago, and office jobs just a few decades ago.

Hmm, so what exactly is a healthy lifestyle?
