Oooh, ruffled a few feathers there ..... :>)
Not a lot of cops in Canada were soldiers before becoming LEO's. And they aren't the only ones who experienced pain or injury in the course of their working lives.
I served 12 years Regular Army, during which I came out of an airplane 318 times from as high as 13,000'. That's a lot of bumps to the body. In civilian life, I spent 15 years responding to blowing gas incidents when I wasn't welding and installing gas mains and services. The next 13 years were spent doing the same thing as a technician/gas fitter on the other side of the meter.
As for danger, in Canada, being a LEO doesn't make the top ten most dangerous jobs. Fallers, firemen, electricians, miners and other trades are far more dangerous.
I learned in the Army that a large 'machine' requires a lot of fuel and downtime to keep running efficiently. The guys I was happy to be with in a bar fight were the first to crap out when the going got rough and we had to go without sleep or food for just 72 hour exercises. It was the small, wiry types that could run on 'empty' the best.
I just bought a magazine that covers all the US special forces units - Rangers, Green Berets, SEALS, etc. A SEAL is quoted saying that the best SEALS are the guys that weigh 145 lbs soaking wet. That's what I weighed as a soldier and it's my current weight. Takes work and effort to keep it there, especially since my wife is a "foodie", a retired Home Ec teacher.
I do it for the sheer joy of it and because life has been good and I intend to enjoy a lot more of it. A bout of alcoholism and a little tussle with the 'Big C' made me appreciate it even more. Every day is a bonus and I try to deserve it.
"The only easy day was yesterday."
Peace, brothers.
