As I said, in my other reply, it's not you that concerns me, it's the physical limits of those who would try to save you in a dangerous situation put at risk because of your size. It's not about the fitness of the individual; it is about the safety of the team.
That’s the deal, you don’t attempt to go up by helicopter. There are these football shaped (look like lemons) emergency boats you go down to and get picked up by boat.
This is really a non issue. In a true emergency, helicopters are an hour away, at best. You can scramble down to the evac boats and launch in 3 minutes.
