I recently learned that 4 of my friends can't swim, and I can't either. I'm wondering how common it is.

swimming is awesome. It's so relaxing, cooling, it also doesn't burn me out like running does. If you go for swimming training (mildly competitive), its also nice because there might be girls there. IMO if you usually see a girl wearing something conservative like a one-piece swimsuit, then, one day you see them in something like a bikini, it's so much hotter.
