Ringo looks fantastic for 80. And this was a guy who went toe-to-toe partying with Keith Moon in the 70s.
In addition to (as you note) him being in great shape for 80, he outlived (and maybe outpartied) Charlie Watts, Bonzo, and Moonie. That's quite an accomplishment.
Finally, I'll say this...when there were no monitors on the stage or any way for John, Paul and George to hear themselves over the screams, it was HIS drums that cut through all that noise so the band could keep it together.
On some level, Ringo may be the most metal drummer of all time.
If someone called me Ringo, I'd wear it as a badge of honor.
