I just read in the news about the FDA approving a new artificial human heart that can replace some transplants, and it got me thinking. The way that science is moving, someday it may be possible to live forever by just replacing our old organs as they wear out. The question is, though, would anyone want to live forever? What do you guys on the BOC think about this issue: If you could live on earth forever, would you? If yes, why? If not, why not, and also what would make you change your mind?
