Tired sense of humor

Does your sense of humor change as you age? I am not talking about aging from teenager to adult. I think my sense of humor must have changed through the last two decades.

This comes up in a when I am having trouble sleeping. I have been watching Jay Leno's last week on the Tonight Show - a program I used to enjoy. While it is still the best of the late night shows, I hardly ever crack a smile - and who are those guests?

I can't imagine the Tonight Show with Conan O'Brian. He is so immature and his humor is just dumb. Did people feel this way when Jay Leno took over from Johnny Carson?

After the Tonight Show, there is Late Night then Late, Late Night, or whatever it is called. Unrecognizable hosts do a lot of physical comedy, jump around on stage during the 'monologue' and seem to continue the monologue instead of interviewing whoever it is sitting in the chair.

I need to get some sleep - I am feeling way too old and grumpy.
