You are stranded on a tropical island. What 3 items would you want to survive?...

I'll take just one item, a "How to Survive on a Tropical Island" book..

PS- Tom Hanks did alright in 'Castaway' when he was washed up on the beach with absolutely nothing, so so I suppose if there's enough water and food we'd be able to do the same by learning on the job.

Go Tom!
