DOES FEEL GOOD: The sense that I am getting my fitness back ("back"? Really?) and could maybe run away from a very slow, possibly wounded, predator.
DOES NOT FEEL GOOD: Walking into the (otherwise empty) change room to find a (male) cleaner mopping the floor. Am I seriously expected to take my clothes off in front of this guy or do I just pretend to be super interested in my little locker and the two pairs of shoes within it? Enquiring minds want to know.
