However, Brady is adamant that he wants to continue playing despite his advancing years.
"There's nothing that can wake me up at 5 o'clock in the morning on a Thursday morning in May like getting ready for a day of football," Brady told TheMMQB.com. "I want to play a long time.
"There's nothing I like doing that's close to football. What'll I do when I'm done playing? I don't know, but I know it won't be nearly as fun.
"I can tell you neither me nor Peyton [Manning] will probably be very far from the game of football when we're done."
Brady threw for 4,343 yards along with 25 touchdowns to 11 interceptions in the 2013 season.
