Uh Oh - 40

I spent the day with a friend yesterday who was celebrating her 40th birthday. Delightful though the day was, the elephant in the room was her singleness. Well, it was until we started to talk about it and it wasn't so bad in the end. But she has decided to put her skates on and give it all another try. 

So how possible is this? Because the more I talk to the single middle agers out there, the more it doesn't seem to be all that likely. Is it? Have you found differently?
