John Travolta Blames Nocturnal Living on Childhood  6/20/07

Actor John Travolta credits his nocturnal lifestyle to waiting for his mother to come home from work until two in the morning each night.

The Pulp Fiction star has never managed to shake his night owl status, and now uses the early hours to complete tasks when he has a bit of peace and quiet.

He tells U.S. TV show Extra, "Since I was five, I've always been nocturnal.

My mother did theater, she'd come home at two in the morning and my dad and I would wait for her. I never got out of that habit.

"I fly sometimes at night. I catch up on all sorts of business I have to do.

I work out. I do my work out at night."
