Chances of coming out alive: 8/10

White water rafting is an extreme holiday favourite and providing you can swim, isn't all that dangerous. You get to choose the course which would suit your needs, unlike the aforementioned skydiving where you can't ask the pilot to "fly over haystacks only please".

If you're an average guy the actual boat trip will be fine, but it's the getting out of the boat at the end which becomes an embarrassing and water-filled slapstick moment.
