I like it! I laughed! But then I got to thinking about how accurate the analogy is. I know it's a joke, but thinking about it lead me to research and I came up with the following:
1) Pee doesn't sink to the bottom of the pool after 8 minutes. At least I don't think it does.
Airborne droplets tend to stay airborne for about 8 minutes.
2) Most cloth masks are probably as effective at containing COVID as a bathing suit is at containing pee. But both will decrease the velocity in which the contaminant enters the environment. A baffle, if you will. Hence, a mask/bathing suit is likely to cause the concentration to remain closer to its origin than an unmasked/nude bather who might project their contaminant further away. Volume increases with the cube of the distance. This is not the complete story on diffusion, but think of talking/weak stream peeing as spherical, while coughing or a strong stream might diffuse more as an *
ellipsoid. The sphere and ellipsoid may have the same volume, but the ellipsoid reaches further from the origin. Then...diffusion takes place as the particles/pee spread in all directions to equalize their concentration. In the case of COVID, this diffusion takes place over about 8 minutes before it settles to the ground. In a pool, the pee continues to diffuse to the point you are almost guaranteed to ingest some if you stay in the pool and accidently suck in some pool water.
3) Pee, while gross, probably won't make you sick if you ingest it from someone in the pool nude or in a bathing suit peeing more than 6' away.? Also, we don't tend to intentionally ingest pool water. So while icky to think about, it probably has a minimal health effect on other swimmers.
As someone mentioned earlier in this thread, masks are most effective when combined with social distancing. How effective depends on a LOT of variables, such as type of mask, viral load of the breather, activity of the breather, distance from the inhaler, etc..
*For you math geeks: Yes, I know a sphere is actually just a special case of an ellipsoid. Also, the ellipsoid/sphere is a simplified model, considering we don't actually breath out of a 360 degree hole in our head, nor pee out of a similar orifice.
Follow the science.?
