Age indicator

It is always good to meet up with your friends and enjoy some good wine. Not just for socialising but also to get informed about your good friend who happens to have a lunch date with one of her supervisors.
Sitting together in our bar, she and her colleague could not agree on the age of the guy.
“I guess he is about 50 +/-.”
“No way! I would say 40 +.”
“Come on, you just want to whitewash the situation!”
Being not really involved, all of a sudden I became the leading lady in the age guessing game!
“We just send Peggy. If he approaches her we know it for sure: He is 50+!”
Oh great, my attraction for old men beyond the Viagra free manliness is finally helpful for once!
