Quick Birthday

Today is the 37th birthday of a man who has come to my attention recently, not for being attractive (though I'm sure someone loves him) but for being the new Master on Dr Who: John Simm is celebrating his birthday today (as is my brother-in-law Adrian).
I also forgot to mention that yesterday was my brother Kevin's 40th birthday. And what else do all three have in common?

The fact that I haven't got a birthday card for any of them! Oops.
