Truth or Dare

A close friend of yours is gonna die (heart attack) in exactly 72 hours. They have no clue about it, only you do (you can tell them if you want), and the death can't be prevented. What do you do? Truth (please do not return me this one, I've got absolutely no clue :P )

@punhero: I wanted something short and positive. I picked this one because in online games I tend to say "good luck have pun" instead of gl&hf ^^

@panda: Would you like a society with human genetic selection? (like in the movie Gattaca, basically for every gene of a future child, parents, advised by doctors, can decide which combination of traits they wish to transmit) Truth

@Daggera: A vaccine gainst AIDS has been invented. But it has been made in a lab run by Shiro Ishii with money collected by Adolf Hitler. Do you use it? Still seek truth
