LeBron James finds the longevity of Tom Brady "inspiring" but not necessarily informative for his own aspirations.

"I've been watching him for quite a while now, and just to see him go out and do the things that he's done in his career, for him to win another one yesterday in the fashion that he won, it was pretty cool," James said. 

"It was very inspiring for a guy like myself. But two different sports, two different positions.

"I don't know how long I'm going to play the game. I don't know how much more I'll be able to give to the game. The way I feel right now, we'll see what happens. But I have no timetable on it. I have no year of, 'OK, do I want to play until 30-this or 40-that?' The game will let me know when it's time, and we'll figure it out then."

James signed a two-year extension with the Los Angeles Lakers before the start of the season, which will take him to the age of 38 through the 22-23 season.

"I haven't [thought about it]," James said in December. "The bottom line is I'm going to stick around this game. I've never taken for granted every time I get an opportunity to play another season. I try to prepare my mind and my body and my spirit for a season, and see where it takes it me. 

"At the end of this contract, I'll be in Year 20. The best thing about it is the year I'll be a free agent will be the same year my oldest son graduates high school. So I'll have some options to see, for me personally, what I want to do forward, being around my family, being around my son more or continue to play this game I love with great health and great spirits. We'll see."
