Imagine it if that happened to you!!!
A certai amount for me would have to go to charity. I would put most of it in the bank to add interest and then the rest wuld go on normal things like houses, cars, holidays (stuff I will be able to get when that bit older!!) Clothes, give up my wkd job, give some to my friends and family - the list would be endless.
But it doesnt necessarily mean that it would give me complete happiness - money comes with baggage.
