Back in the day when I was on Facebook (took myself off a couple of years ago) I was sent "friend requests" from about three or four ex-girlfriends from years gone by.
All of them were looking considerably older, saggier, and judging by their desperate attempts to regain my friendship and affection I realised I had made the right decision by getting shot of their asses when I did. Women do not age well (especially post-childbirth).
