I was gonna say exactly what Lennonlemon beat me too...
I was also thinking that maybe Paul would live last because he's a robot...
But Ringo should be next in line for being Santa Claus... Don't know how many years that lasts...
Unfortunately, when they both die, the world will seem empty to anyone who has ever heard any Beatle song, ever... If you can feel it, it seems a bit half-empty without John and George...
All I know is that I hope both will live on as long as they can...
Paul seems to be the one getting the surgery to make him look younger, so he'll probably be the first person to try any vaccines that increase our tiny life spans, if they ever come up with them.....
We'll see... Sadly, we'll see...
