Umm... that's why you pee before you get in the pool. 100 yards isn't that much to ask to avoid swimming around in your own, and other's piss. Those kids will be swimming around for hours exerting way more energy than the walk to the bathroom. FFS. This is why I don't swim in pools.
At the very least, you shouldn’t stick your head in the water, and swimming in shallower areas exposes you more strongly to contaminants than in deep areas.
Yeah, don't care. The mental image of 1000 kids peeing in the pool, and the same water being in it for months on end grosses me out to no end.
I also honestly can't imagine what is worse than human piss and shit. Maybe those leeches that swim up your dickhole? I don't think there are any of those around here. I'm genuinely curious what is worse...
Wait until you find out you splash yourself with urine every time you use the toilet. Or that millions of bacteria are defecating on you as we speak. It's all in your head, these things are not harming you.
