A few years ago I taught a man in his 50's Open Water SCUBA. My requirement was for persons over the age of 45 to have a complete physical prior to taking the class. This man did that very thing.
I don't remember his status at this time, as far as diving is concerned, but one thing really stands out.
One day, at the store, he showed up. We had casual conversation, and then he said, "I want to thank you for saving my life". I thought about an old dog joke at the time, until I realized he was really sincere. I asked what did I do that saved his life.
He said that if it wasn't for the requirement of a physical - - he had not had one in years - the doctors would have not found that he had prostate cancer. He said it was found soon enough to remove it without any complications. Can you imagine how I felt after he told me his story. It does pay to have frequent physicals.
A different story, but interesting.
