(I escaped to an aircraft hanger, then on to a desk job, thank you Jesus)
I'm that 60+ year old guy you were looking at when you were a kid. I'm 65 now, and only hung up my tool belt for good when I was 63.
I worked outdoors a good many summers in the same area where this postal worker died. I also spent ten years working in the Texas sun, after the age of fifty.
Did I hate it? Hell yeah, but I'm not complaining. It was my career, and I made more money doing it, than my cubicle bound brothers ever did, in their air conditioned, cushy careers.
