He has contraints about depth. We still swim and body surf so I was hoping that the depth would be less, maybe 10 feet and with me at his side if he became unconsousin (unlikely) that it would not be as dangerous as being down 100 feet. He can't sky dive either or rock climb, but we don't do that. He can play, drive, just can't be where he might die if this "vasal-vagal" thing happens.
