The stereotype says men LOVE young women and think women start losing their looks as soon as they pass, like, age 20.  But women aren't quite as superficial . . . they see older men as more distinguished and handsome.

That stereotype is a STRAIGHT UP LIE.  According to a new survey from AskMen , women are WAY crueler when it comes to judging the other gender for losing their looks.

The average woman says men start losing their looks at age 30.  The average man is much more generous and says women start losing their looks at age 40.

31% of women say men lose their looks at age 30 . . . 22% say men NEVER lose their looks . . . 17% say men lose their looks at age 40 . . . 16% say age 60 . . . and 14% say age 50.

40% of men say women lose their looks at age 40 . . . 21% say age 50 . . . 18% say NEVER . . . 14% say age 30 . . . and 7% say age 60.
