Can the elderly host a show?

I'll be honest, until tonight I rarely get excited to watch an episode of Saturday Night Live. Betty White is gearing up to host this weeks show. At age 88 she will be the oldest host yet. Now I only periodically watch the show and it's really just to see the digital shorts. But tonight i want to see Betty White excel which I expect her to. It also doesn't hurt to have Jay-Z perform, who could be the only rap artist that I can stand. I guess we'll see how the former Golden Girls actress performs. Tonight will be one pf the few times a cheer for the elderly...I hope she can remember her lines.
