It was a treat for those who watched James explode on his birthday. But what is the LA Lakers' superstar secret to longevity?

"Making sure my body stays fresh, but my mind more importantly," James said after the game. "As long as I keep my mind fresh, then my body will follow what it may. It's always good to come out here with my teammates. They worked their butts off tonight.

"After starting 1-for-5, I didn't know what was going to happen. But just going out there and playing with my teammates, it's been a decent road trip. ... We want to finish it off the right way."

The LA Lakers improved to 2-2 on their current road trip, with wins over the Atlanta Hawks and Orlando Magic. They will finish it off against the Charlotte Hornets on Monday.
