I'm certainly not preoccupied on how they look. They could be all wrinkly, grey, and hunched over for all I care. If I look like Grace does when I'm that age, I'd be very happy with it. For being in her mid-60s I think she looks fantastic. I was simply stating, that not having seen pictures of them, and not being around for 40 years; I don't know how time affects people like that. And sounds like a great show though.
Edited to add the word not, because if I didn't it sounded rude and had a different meaning.
