please excuse the nerdiness, but thought people might be interested to see kayakers enrolled in a scientific study published in a major journal. apparently a bunch of paddlers/spectators at the 2007 Nile Freestyle Festival were checked for schistosomiasis (bilharzia) infection. anyway, the study concluded that if you paddle (raft or kayak) the nile, you have a 17% chance of being infected with this wormy parasite. so, get yoself checked before the worms eat your liver.
