There was a book written about how this fellow found diving and challenged himself with ever more difficult technical dives.
I started the book knowing that the man had died in a diving accident, but I read with a deep sense of forboding, wishing that he would quit while he was ahead. He didn't, of course.
I am a sport diver and am certified as a rescue diver. There is no possibility of Dave having been rescued from where he was. Just the thought of a dive deep enough to require hours of deco coming up is daunting to me.
Dave died challenging himself at known limits.
Maybe that's better than dying while resting in bed?
Maybe not, for those who survive the fellow who dies doing something potentially deadly with no real purpose.
Still, a brave man who died doing what he wanted to try doing.
