It is true that there are a lot of deaths in 'extreme' sports. And people push themselves too far. But I think swimming is an exception. If you are running and in a 'fog', or being 'out of it', because of exertion, then fine, eventually you drop. But in Swimming, the risk is super high, you die. If in the water, and distressed, then the life guards should be able to over-ride someone waving them off.
