His hair does appear to be somewhat thinning, and he apparently doesn’t particularly care if it is neat. He doesn’t particularly look bad, though he is showing his age a little. He’s 70, so he’s in good shape.

He appears to be going for “deadpan” in that interview. That, and a bit perplexed by Jon.
If you notice, he’s always been kinda deadpan. I remember seeing him on Merv Griffin or something in the '70s and his face has always shifted around slowly like that. Then when he smiles, it’s delightful, and so we smile too.
