A metaphor I was thinking of earlier.

If a guy is going to piss on you, you're going to be happy if he has to keep a pair of speedos on as he attempts it. You could also just move further away from him.

But if you're both swimming in the same pool while he pisses in it, those speedos will make little difference anymore. Neither will your distance from him help very much.

What will help much more is the amount of water in the pool, and the amount of fresh water being pumped in and old water pumped out.
