Uhhhh.
Uhhhh. - 

Here's a pet peeve about how I sound on the radio: When I listen back to myself in interviews, I'm struck by how often I say "uhhh" as I'm putting together a question. I think it makes me sound stupid, but it's how I talk, so I roll with it.

Turns out I'm completely normal.

A post at the Atlantic quotes a linguist at the University of Pennsylvania, who says men use "uh" more and more as they get older.

Women tend to say"um," but that decreases with age.
