Comedian Richard Herring turned 40 and bought a skateboard. He still wears his Converse trainers, and purchases tight-fitting T-shirts to look cook, despite the obvious belly bulge.

Because if I am going to deny the fact that I am old, I might as well deny the fact that I am fat as well. 

Holy lord, he knows me. Inside and out.

Most people would call turning 40 and suddenly trying to look and act like a teenager a mid-life crisis. But what if you never stopped acting like a teenager to begin with? Is that just who you are, or should you just strike out the "mid" and admit you're in a permanent life crisis?

Herring has a name for these hip Peter Pans -- "Kidults."

Here are the signs. Be warned. You may recognize a few of them and have a sudden desire to buy tweed and make your kids call you "sir."
