Military and Law enforcement are fitting occupations for young men at the peak of their reflex speed and ability to heal. They are not a great match for people staying until retirement.
I was taught this and why it was by my grandfather, and recruit training stressed that the military wasn’t there to give me a retirement.
Not that most of the law enforcement in this country will collect their retirements, as the ponzi scheme is reaching its end.
Cops aren't military. Big difference. From my experience, I'll take a senior seasoned cop any day over some young guy with a heavy badge thinking he's going to be the ultimate crime fighter.
