> The cultures of the world that live the longest do not do organized exercise: http://blog.ted.com/2010/01/06/how_to_live_to/

Were we ever talking about living longer? Exercise is important because improves blood flow to the brain, and therefore brain function. It can make you happier and better rested.

Longevity is impacted by a lot of other lifestyle factors, many of which have nothing to do with exercise.

So basically you're conflating those other cultures' incidental lack of cardiovascular exercise with the fact that they live longer (which is due to completely unrelated factors), and then making the specious claim that exercising leads to shorter life spans.

> Going to the gym is largely an Americanism. Not exactly a culture I'd want to emulate for healthiness.

Going to the gym isn't an "Americanism", it's something done by a certain percentage of Americans who are significantly healthier than the American population at large.

The fact that you're even suggesting that intense exercise at the gym is bad for your health is just appalling.

> Consistent movement is much more healthy than sporadic bouts of high intensity. Walking everywhere is just about the healthiest thing you can do.

I never said that you shouldn't walk around, it has its benefits too. My point is that "walking around" is not "exercise".
