as a cop who has tried to stay in shape throughout my career it's tough to see some of my co-workers have let themselves go over the years. Unless you are on walking beat or bicycle patrol, police work is mostly sedentary. Lot of driving, standing, a little walking and the ocassional burst of cardio for short periods. Many meals consist of whatever drive thru is open at 4 am and you eat sitting in your car. As a Detective it's even worse. So if they don't take it upon themselves to make an effort to eat right, and get excercise after work, eventually they look like crap and die shortly after retirement. There are no weight restrictions allowed per ADA rules, it's up to the criteria "can the person perform the job" and it's not really challenged very often. I've seen a Fit for Duty inquiry about 3 times in 22 years for some extreme cases but it's not common. It's embarrassing to me when someone is a physical mess in uniform.
