- Most of his dives look to be rec depth
- He isn't running any crazy gear like a CCR
- He has instant access to a chamber, so any DCS worries are virtually zero
- There is no go-itis for him. If weather is bad, he just packs up and sails to somewhere nicer
Out of all the rich people hobbies, scuba is about the safest
Scuba fatalities fall into a few buckets, the big two are inexperience/bad decision making, and older folks with health issues (underwater heart attacks/respiratory distress, basically).
As a former dive pro, an overweight 63 year old is someone that I would keep a very close eye on while diving.
The odds are pretty low, but there is a reason that many life insurance companies exclude scuba divers from their coverage.
That said, I'm happy to let him live as dangerously as he wants, he deserves it.
The most common reason people die while on scuba is running out of air, if you always buddy and you have a bail-out cylinder that should be essentially impossible while rec diving
"but there is a reason that many life insurance companies exclude scuba divers from their coverage."
They will refuse to cover you outside of rec diving because of all the reasons I just stated
As I stated, the most common way to die diving is from a heart attack or other health incident according to DAN. Running out of air is a very uncommon cause of death in rec diving absent a primary factor like entanglement. So no, you are absolutely not reducing your chance to 0 by doing everything right. You are eliminating the chance of suffering a death from one of the things that doesn’t kill a lot of divers. An overweight old person doing an activity that stresses your lungs and circulatory system in an unforgiving environment is inherently high risk no matter how thorough their skills and preparation.
Double check your health insurance, many exclude rec diving as well.
Every single dive instructor has a story of seeing an old guy have a heart attack, myself included (he survived, barely). The only other death I know of besides old guy heart attacks where I worked was a young guy that had a heart attack.
There's no nice way to say this, but maybe you need to re-evaluate your relationship with this video game company.
