Great article about novelty-seeking being an enemy of actual health improvement (because it becomes an end in itself): http://www.mensjournal.com/everything-you-know-about-fitness-is-a-lie/print/

An information worker should have an easy time translating it into practice: find out what actually works, from someone who knows, and do that. As it’s all new to you, there will be plenty of novelty for a long time before you become genuinely bored. If you bring intention, attention will follow. Forget externally-driven pseudo-randomness (Wii or fitness trainer) and find joy in the varieties that you are always immersed in. Programming a hill into your treadmill is not the same as deciding outside whether to take the ramp or the stairs, whether to quicken your pace or stop for the view, etc.

Of course, as in your Crucible post, a blend of competition and cooperation pushes people to try their best and expand their limits. Meaningful brain chemistry comes from making decisions and acting on them, not from reacting defensively to what’s thrown at you. Perhaps that’s why many people organize themselves into sports teams with around 12 members rather than exercising alone.

Therein lies your objective definition of “Healthy”. Before we became zoo animals and had various degrees of “life support” keeping us marginally alive well past our primes, what was the objective definition of health? Answer: How well could you hunt mammoth? We use the equivalent of this definition all the time, for example in speaking of someone who recently died: “At least she didn’t suffer and she was healthy, able and independent right up until the end.” Clearly in that context “healthy” does not mean “far from death” because the statement is referring to someone who died. Healthy means capable of doing stuff.

If you want to be healthier then do more stuff…preferably constantly varied functional stuff performed at high intensity.

I may or may not have drank large quantities of kool-aid, open to debate
