Men in their 50s?

Why is it that some (quite a lot I have heard) men in their 50s feel the need to have one last mad dash to relive their wild oat sowing days??????? What the hell is it all about? I know the male menopause is a real thing, but to give up your family and many years of marriage, WHY? I pressume what little brain they do have in their heads migrates southwards to their and all sense disappears. I am not a man hater, just one!!!!!!!
