Urinating in a wet suit will leave a trail of urine for quite a long time as the urine first leaves the wetsuit in signifcant volume and then as traces are rinsed out of it . . . Shark attacks are quite rare, but it's not a good idea to tempt fate.
I remember jamie & adam trying to bust this myth on one of their specials during shark week. first of all lemon sharks are
not interested in our urine
, second of all, their sense of smell is not that acute, they can't smell a drop of blood from a mile away.
Warning -- they only used lemon sharks
, results may differ with great whites
