OT, met a 60-year-old lady today in a mundane office, (Board of works equivalent) no make-up no big boobs, OK looking, nothing special except you could've sworn she was not a day older than 40. Honest. Only learned her age because we were talking about retirement.
There are a small number of very well preserved senior ladies out there. They tend to have lived pretty healthy lives. As I get older, and with all that extra experience, I find it almost impossible to age people accurately. Doesn't pay to get it too wrong.
