Drownings not as bad as it seems. Those who spend a bunch of time in the water see people drown quite a bit. You black out before you drown. Then a minute or so later you really drown.
I've pulled people out of the pool who were in between. They would be struggling, go limp, drift to the bottom and then we would jump in, bring them up, pump them out and throw them back in. Tell them they needed a bit more work on their technique.
LOL. My kids swim and two are now lifeguards. I can appreciate that. I couldn't swim if my life depended on it. I avoid water except the beach part.
