Bleeding nipples

You read right. Bleeding nipples. This is apparently one of the many possible side effects of running, one I never could have imagined.

Peter has taken up marathon running and has joined a running club to train with. In this morning's run, the nipples of a guy running with him started to bleed from the chafing of his shirt. It was, of course, a white t-shirt. Thank God Peter took the hint and took off his shirt, because the minute his nipples start to bleed, I might just have to put an end to this nonesense. Or just rip off his shirt :-)
