Tom Brady, who will turn 45 next month, knows he doesn't have a lot of football left.

"I really don't (know when I'll be done playing)," Brady said in an interview with Variety.

"I would say it's year to year: Could this be my last year? Absolutely. Could I change my mind? Absolutely. I've realized I don't have five years left. I want to do it my way. I want to give it everything I got and see where I'm at. My body feels really good. I've had a lot of traumatic injuries over the years, but if things go really smoothly and we win, that'd be great."

Brady retired in February before returning to the Tampa Bay Buccaneers just 40 days later.
