Drop Dead by Babette Cole
Bald and wrinkly' Grandma and Grandad recall to their grandmother their entire lives which have been more colourful and bizarre than anyone could possibly imagine. Adventurous babies, outrageous school children, disastrous and experienced teenagers who grow up to be a stunt man film star. . . But despite the hazards they have survived, they expect one day to just drop down dead like everyone else. But their story doesn`t stop there, because once dead, they could be recylced as anything. . .
