I was Scuba diving in the Maldives and this German guy we were with suddenly got a really bad ear bleed (it happens if you go down too quickly)

Anyway, he had to abort the dive as he was attracting sharks whose behaviour was getting more and more aggressive. The more blood there was in the water, the bigger the sharks it attracted.

I know this thread is supposed to be about nosebleeds, but I thought I would share this one with you as it was a SERIOUSLY inconvenient time and place to be bleeding !!!
