Exercise, Heat, Cold & Other Stressors for Longevity | Episode 3

If you fast forward to now, our society is built on comfort ... Most countries have enough food and shelter; we can sit down; we don't have to run away from predators very often.

The body doesn't expend energy to defend itself unless there's a need for it, and modern society is the worst thing.

Exercise isn't just beneficial for your fitness and for your vitality; it actually can stop diseases in their tracks. Exercise can slow down cancer. In fact, it can prevent up to 23% of all cancers from occurring.

There's absolutely no doubt that men who partake in sauna bathing a few times a week... have a dramatic reduction, up to 20%, in the rate of cardiovascular disease and mortality caused by heart attacks.
