New England Patriots quarterback Tom Brady has made a career out of besting Father Time. His personal trainer Alex Guerrero is confident that he can keep it up for almost another decade.

Brady has made it clear that he hopes to play until 45. According to Marcus Kwesi O'Mard of NESN, Guerrero feels his client could play until 50 if he truly wanted to:

“I mean, why not?” Guerrero said. “I’ve never put limits on myself, and I’ve never put limits on any of my clients. I’m a big believer that everything is learned behavior. You tell an athlete, ‘You’re gonna be done when you’re thirty,’ well, the brain begins to believe that, and all your neuro-programming is based on, ‘OK, I’m thirty, I’m old.’ But I don’t think the brain understands the concept of time. It doesn’t understand age. Right? How would your brain know you’re whatever age you are? I always tell Tom, we’re not gonna tell our body what we wanna do. We’re gonna tell our body what we want it to do.”

The prospect of any professional athlete competing until they are 50 years of age seems a bit far-fetched, especially for an NFL football player.

Of course, he has defied the odds in recent years as both a 40-year-old MVP and Super Bowl champion. Becoming a 50-year-old quarterback could be the only accomplishment worth pursuing for him at this point.

Although Brady's production declined in the 2018 campaign, there is no question that he is still one of the league's premier elite quarterbacks. It certainly helps that he is a part of the most well-run organization perhaps in all of sports.

Only time will tell whether or not Brady truly plans to retire at 45.
