Okay -- a seizure or medical event could always happen, but that's why I said the swimmer (or poolside person) is monitoring. Bubbles stop, or you start having a tonic-clonic seizure -- somebody goes after you. Do a bad entry and whack your head, the person monitoring you is going to see that.
And if you are so overweighted that you can't swim up the sloped bottom of a 12 foot swimming pool, somebody really doesn't like you. I mean, even I can hold my breath long enough to get to water shallow enough to stand up in in an Olympic sized pool.
Is any immersion in water utterly and totally safe? No. But at some point, you have to get realistic. I don't think you have to have somebody on scuba in a pool with you every time you get in. I think it's probably a good idea to have somebody monitoring you, but I'll admit I've solo-dived in my backyard pool because I think the risks of doing so are probably smaller than the risk of driving to the pool the LDS uses . . .
