Old skiers usually have beards

Women live longer, but men ski longer. At least, that's what studies suggest.
According to a story in the Vail Daily "Research by the National Ski Areas Association shows that women make up a declining percentage of skiers as the population ages beyond 40. At age 40, women make up just under 50 percent of skiers. At 47, women make up 40 percent of skiers and snowboarders, and by 67, just over 30 percent of skiers and snowboarders are women."

Why? The study cites possible answers, such as that women like to ski in groups, and as fewer and fewer are able to ski, they discourage women still in skiing shape. I'm sure there are a number of other factors.
I will say, though, that I know at least four women over 60 who are better skiers than I am. And I'm happy they still hit the slopes, because they're usually willing to give me some pointers.
