I think it was Ken Friedman who said that he thought that 75% of us were doing too much and 25% were doing too little. I guess that means that no one is doing the right amount (lol).The "doing too little" thing to me smacks of the deconditioning/exercise phobia hypothesis. We have a hard enough time holding ourselves back from doing too much even when we're really sick. I really can't imagine someone that is doing better holding themselves back too much.
My experience has been that my activity level dynamically expands or contracts to fit my capacity for it. The limitations I impose on myself are constantly calculated by watching symptoms. If I was asymptomatic, I would impose no limitations.
