It would be cool if he was still alive. In the world of Avatar it's not impossible. Bumi was still fighting strong at 112 and the Guru able to move around better than many guys 1/3 his age (he's over 150 by the way). Kyoshi managed to live to see 230 years old. She was dubbed as the longest living Avatar, but NOT the longest living person.
I'm fixing that immediately. I rather like the idea that these two would be all about the tea.
SQUEEEEEEEEEEEEEE
