For the water worshipers among us.
 
Anyone see the US based study on 31 public swimming pools? I think CNN first reported it.
End point recommendation was you will be better off swimming in your toilet.
 
Some of the findings quite inspiring and unique. They did pull back and say that there is no guarantee that swimming in an ocean or lake is any safer, but swimmers beware.
 
Crux of the report is that public swimming pools are a cess pool of filth. Many bugs rampage thru the chlorine and infect anyway.
 
Was a plea to moms and kids to shower first, not crap and piss in the water. Yeah right...
 
My own nefarious past as a kid, was never a thought of walking out of the pool to a toilet. Just piss and everything is diluted.
 
Wonder of biology is osmotic pressure. Means something more dilute trying to equalize something more concentrated across a permeable membrane. In this case, water on the outside, blood on the inside and skin as the membrane. After a few minutes in the pool, the body gorges with an influx of water that has to go somewhere as the kidneys fill up the bladder to get rid of it.
 
How many kids Boy Scout's honor are going to void outside the pool.
 
Interesting things in the study.
 
Eye irritation in the pool is not from the chlorine, but the interaction with chlorine and urine causing a toxic mix.
 
Even more inspiring is the touchstone of contamination you can do yourself.
 
Taste of the pool water. Since kids (and adults) are maybe drinking artificially sweetened cokes and diet drinks, and because the taste sense of these agents is so sensitive, someone pisses or craps in a far end of the pool and you will be able to taste the sweetness in the water. Thus, the more sweet the water tastes, the more you are sucking up feces and urine.
 
Is this cool or what?

I used to swim 60-80 lengths every morning. But then I realized the chlorine wasn't doing me any good. It's not good for your skin, it stains your teeth and weakens your enamel, and I also read somewhere that your sweat reacts with it to produce a carcinogenic gas which hovers just above the surface of the water so that you get a nice lungful of it every time you come up for air. 
 
I did hear that there are now chlorine-free pools which clean the water via a constant intake through a pipe which zaps it with UV and kills all germs, which sounds great, but then of course you have to consider that if someone does pee or worse in the pool, you might get exposed to that water before it's had a chance to go through the UV pipe. 
 
So I guess there's no way to swim and avoid everyone else's filth. Then again, is anywhere safe? Just think of what you might be sitting in when you take a seat on the bus or train, or what you're touching when you grab a door handle or stair rail. 

So would it considered extreme to wear a hazmat suit 24/7?

That's it!  When I can afford to build my own house, I'm putting in my own lap pool!

So you can swim exclusively in your own crap ?

For goodness sake. You can spend your entire life reading 'studies' and worrying about stuff like this. Just go for a swim, the benefits from it will far outweigh being in contact with a little bit of wee-wee

Pee is sterile though.
