My grandfather's doctors told him at age 30 he would not live a long life. He survived to 95, outliving some nine doctors.
If diving after age 50 shouldn't be done, I guess I've overcome the odds for the last 10 years and have done (without question) the most intense diving of my 47 year diving "career."
