There might be many different reasons. Regarding that specific case the issues of subjective and objective pain migh be a hint to a broader explanation. I also know that different individuals will objectively feel pain in various degrees for the same stimuli(not sure about the spelling). Time needed to restore the body to a "normal" or relaxed/replenished state after physicial activities isn't the same from one individual to another. An another social theory also states that people tend to get fat/lean, give up smoking/etc., when most of their social connections do (even though they aren't in direct contact with them). Citation needed, will dig later after it but not sure if i can find it again.
