You can have my fins when you pry my cold dead fingers... oh wait. That's the whole point!
I don't do much deep anymore. 130 is deep enough. It's not just age, it's skill and comfort.
Remember Bill Rennaker's heart attack?
He had a heart attack in a cave, and slowly swam back to the entrance, breathing O2 from 9M. Used up all his own O2, had his buddy leave his O2 with Rennaker while the buddy exited and arranged for an ambulance. Several hours after EMS showed up, Rennaker exited and they whisked him off to the hospital.
After all the examinations at the hospital, the told him that he had had a heart attack, but due to the several hours of self inflicted hyperbaric O2 he had suffered no major tissure damage.
If he hadn't been cavediving and had not been as pigheaded as he was, the heart attack probably would have killed him.
