Swimming As Easy In Syrup As In Water
chthonicdaemon writes "Nature is running a story about scientists at the University of Minnesota who proved that swimming speed is not a large function of the viscosity of the liquid. To do this, they thickened the water in a pool with guar gum. Fun ensued. This is the type of thing that usually keeps to thought experiments. Interesting to see someone prove it."
How come I can't swim in air?
This is a false rumor spread by that Canadian-grandmother-turned-sex-therapist who has the womens' network show (which is hilarious, incidentally. Trust me.) Ask YOUR doctor about any advice you see on the show before you put it to practice ("I saw it on TV, it must be true!"), okay?
People have been having sex for centuries in the water- lakes, ponds, rivers, oceans, hot tubs, pools, jacuzis, showers, bathtubs- you name it, people have had sex there- and there's simply no evidence of all these injuries you claim(death? Infertility? Riight. I've even seen people claim women could get air embolisms!) A UK women's scuba newsletter asked women divers about their experiences, and surprise- nobody had an injuries.
If anyone who is actually qualified to speak on this subject can present ANY case evidence of this happening in substantial numbers(linkage, please!), I'll shut up- but I think the parent poster is full of nonsense and these "dangers" are about as "dangerous" statistically as catching, and dying from, West Nile Disease- if at all.
