and what tipped you off to that fact? ...and you were heading into middle age? or employers looked at you and didn't hire you thinking you may cost too much? or going nightclubbing was either too tiring or the people there were too young? or when most of your friends were married or in long-term relationships? or when sex drive slowed down? or when most of your friends who wanted kids already had at least one? or when you looked in the mirror you looked like your dad/mom? or when you walked down the street SOMEBODY thought you were them? or when your hs friend who got pregnant had a boy who is going bald?? (or alternatively, you are biologically old enough to be a grandparent, especially in this ongoing epidemic of teen pregnancies.) that being said, is it harder for a woman to no longer be a "young" adult?
