This sounds like wonderful news at first, but when you think about it a little more, it seems like a disaster waiting to happen — one that only a few SF novelists have even attempted to write about. And of those few, the only one that I’ve read (which, unfortunately, I do not recall the name of) is pretty grim.

Fortunately or otherwise, this research probably won’t turn out to be the human Fountain of Youth. But we’d really better start putting some serious thought into how to deal with it when — not if — it’s discovered. Our biology and psychology ensure that we won’t give up until we find it, no matter how long it takes, or what the consequences might be.
