I wonder if this means we can be enjoying great victories of the mind as the body is beaten - as in a football game, a chess match or getting that (yeah, that one) ONE person to spend some time with us after both fearing the act of trying to [win] and the stress of waiting for the end of the competition. Is winning always happy?
