I have to admit, it is pleasant to be getting old uniforms out the closet because my newer ones are now too big.
For my routine, I work through lunch and then spend the last hour of the day at the gym. I figure that if fitness is a service requirement, then it should be done on service time.
Actually, I'm looking forward to when I turn 45 so I can move into a lower PFT bracket! I really do hate it; my idea of hard work is walking to the fridge for another can. There are only two reasons for physical exertion IMO: lovemaking, and running away from nasty situations.
