Been thinking about this recently as I don't really have a fixed idea in my head as to how I define fitness.

I kinda think I'm fairly fit, but not as fit as I'd like to be. But to an averge inactive westerner, they would probably consider me very active and fit. However my level of activity is far below that of a nomadic hunter gatherer I would suspect.

Be interested to hear other peoples ideas on how they define fitness and if they have achived that level.
