I saw Dianna Rigg in an airline check in queue about 5 years after she left the Avengers, she looked rough as hell, which was a real suprise at the time. I also saw Steed, can't remember his real name, getting into a Jag outside Hove Police station in the early 80's and he looked exactly the same as he did in the Avengers. Goes to prove that men age better than women
