My grandfather at 80 was stronger than some 45-year-olds. I don't think you can argue that age alone disqualifies someone. Old men fought in the American Revolutionary War, after all.
Maybe because your grandfather had been very active physically throughout his life.
He wasn't especially physically active, and he smoked and drank and ate too much salt.

What about Aisha? She had been a celebrity most her life. And as a female in arabia, were mostly at home. Its very unlikely that she had remained fit.
There is no way of knowing whether it was unlikely or not. I've been mostly indoors for the last week, and I haven't been working out. My body maintains itself well regardless. Hers may have had a fast metabolism, or she may simply have exercised. Who knows? Who cares? It's entirely plausible that she was fit enough to run a marathon.
