Los Angeles Lakers guard Kobe Bryant said he is "scared" about his future after basketball.

Bryant, who turns 36 in August, is under contract with the Lakers for two more seasons. He played just six games last season. After he returned from an Achilles' tendon tear, he sustained a season-ending knee injury.

He is the subject of a documentary that airs on Showtime in November. "Kobe Bryant's Muse" looks into his life last season when the Lakers went 27-55 as he recovered from the injuries.

The absence forced Bryant to think more about his future after his playing days are over.

"I'm afraid, too," he said Friday at the summer TV critics' meeting. "You really have to lean on muses and mentors going forward, just as I did as a kid. It's about having that next wave of things, which is scary as hell, but it's fun at the same time."

In 16 NBA seasons, the two-time NBA All-Star has averaged 14.9 points, 5.2 rebounds, 1.7 assists, 1.1 steals and 32.0 minutes in 1,049 games (842 starts) for the Seattle SuperSonics, Orlando Magic, Washington Wizards and Heat.
