[Punisher] How has the Punisher survived being shot, stabbed beaten and strangled so much over the years.

I've read every Punisher comic from the 80's up until 2008. Dude takes a lot of damage.Does he have some kind of healing factor?

The Punisher typically wears military-grade body armor while most of his enemies use civilian weapons. He also keeps himself in top shape, which goes a long way toward recovering from injuries. 

Still, Frank Castle is probably in pain most of the time. He just doesn't care. He has one mission in life, and he'll keep doing it until it kills him. Like Bruce Wayne, he doesn't expect to reach old age. 

EDIT: Setting aside the fact that Frank and Bruce put themselves in harm's way, they are in many ways ideal patients. They have no vices. Their diets are perfect. They'll never forget their medication and they'll never skip physical therapy. They train like elite athletes and recover like elite athletes. About the only thing they have trouble with is getting enough rest.
