French movie actors' longevity.?

I think it is a generation that had to live on very little during and after WW2, refrained from abuse when they became more prosperous, and lived frugally most of their life.They also have kept active, and mixed with a lot of younger people than themselves. Look at the Queen of England, she too has reached a grand old age. She is known to eat very simple food and she has always exercised by walking, or riding when she was younger. At her age she is still able to stand for an hour and a half continuously and distribute honours to over one hundred people. She walks considerable distances for a lady her age and is very active.
