Having had maybe more than my fair share of injuries and made it back from all so far, I have right about no tolerance for cops who are fat, out of shape loads simply because they are too lazy or indifferent to exercise and eat better. It really doesn't take much to be in minimum acceptable condition, but it's way too much to ask of some. There is almost always a way to work around an injury. If you can't run, ride a bike or swim. Just do something, and quit eating at McDonald's and 7-11.
Those who will not work out have nothing those who cannot work out.
