Tom Brady will turn 40 before next season but the Super Bowl MVP does not see himself retiring any time soon.
The five-time Super Bowl champion, fresh from this month's stunning comeback victory over the Atlanta Falcons in Houston, plans to continue as the New England Patriots' quarterback long into the future.
Other than a torn ACL in 2008, Brady has been durable and shows no signs of diminished skills, especially with arm strength and accuracy.
"I would like to play until my mid-forties," he said to The MMQB.
"Then I will make a decision. If I'm still feeling like I'm feeling today, who knows?
"Now those things can always change. You do need long-term goals too. I know next year is not going to be my last year."
Brady was on the field for 99 plays in the Super Bowl LI win over the Falcons - the most in any match of his career - and feels the secret to his longevity is his complete devotion to diet and fitness.
"I have worked hard to get a system in place that really works for me and I know could work for everybody else if they just did it," he said.
"That enables me to play 99 plays as a 39-year-old in the last game of the season.
"Football to me is more than just a sport. It has become my life for every choice that I make - what I have for breakfast, how I work out - all of those things. I love the game. I love playing.
"Taking out some things in your lifestyle [like] going out with your friends until 1am, I don't do that anymore.
"That is making lifestyle choices that support dreams and goals that I have. Football is a job, but it has never felt like a job for me."
