Ya, let alone the toll it takes on the human body.
When i got out of the Air Force in 1980, i has to find myself a civilian job.
Fell into professional auto mechanics, and did that for about 30 years.
In that length of time bending over fenders, crouching down under cars on the hoist, working on your back under an instrument panel, kneeling down, getting back up, i have severely worn out my human body, and specifically my back.
I have a hell of a time getting back up, without a lot of grief these days, doing a simple thing like airing up the 4 tires on the car.
I'm now a walking, medical disaster area in my old age.
And i know it's only going to get worser, as i continue to age.
