I stopped and spun around towards it, an old man was face-down on the deck. I was the closest by far, just an arm's reach away, but I was in the water and pulling myself out without using the steps just wasn't going to happen. I started calling for other people to help.
The guy started waking up, but he had no idea what had happened and his face was twitching oddly. Luckily he listened to me when I told him to stay still. I talked to him for a while while others milled around/went to get cell phones/went to fetch staff. Then unfortunately the man sat up. Luckily someone else was close, because he passed out again and would have hit his head on the bench if someone hadn't been close enough to catch him.
Eventually (too long, in my opinion), staff came. They called 911. Felt like a long time, but eventually a whole pack of rescue people came (6 paramedics and 2 cops). Since I had been the closest and seen the most, different ones kept asking me what happened, so I repeated the story each time and answered their questions as needed.
He didn't want to go, but eventually they convinced him to let them take him to the hospital. While in the beginning I was worried he might be having a heart attack or stroke (the latter especially, since one side of his face had been twitching), it turns out he likes to stay in the steam room a lot longer than recommended (recommended time for healthy people is 5 minutes, he was a 70+ year old man with high blood pressure and stayed in for 15).
So now I wish I had stayed bored instead!
And on the gym? It's equal to or better than my previous gym in all ways but one: The showers in the locker rooms. The Y was meticulously clean. The showers in the locker room in the new gym are GROSS. I've only used them twice now, but I never will again. Hair everywhere. I do not know how women aren't walking out bald, there are such big clumps of long black hair. So gross. Luckily the gym is only 10 minutes or so from home, I can wait that long to shower. (Plus the water gets barely warm, and there's the least water pressure of any shower I've ever been in, while the Y showers were the best ever.) Even with the shower issue, this gym is working out great.
