Galt, If you see someone standing in the road with a speeding truck coming toward them, Let's say you have time to make a conscience decision to let the truck him. The cause of death will still be listed as whatever, you are still partly responsible.
Highthief, There's plenty of donors, there's a shortage of dead ones. (That's not true, but It sounds good.) All the donors on TFP haven't really been harvested yet though
I would like to see a study about any relationship between who is likely to be a donor, and who is likely to die in accidents. It seems to me that anyone that cares enough to give thier organs isn't the kind of person to drive 150mph on a motorcycle and vice versa although I could be wrong..
