Tampa Bay Buccaneers quarterback Tom Brady retired and then unretired earlier this year. The NFL superstar's love for the game is quite clear, but he recently revealed that he almost retired at the age of 27.

"When I was 27, I almost retired from the game of football because of elbow pain," Brady said in an advertisement for his company TB12. "Now, I'm 45 years old and I'm still here. No matter the age, no matter the obstacle, it's about how you feel and about what you do." 

Brady shared the story in trying to prove that his TB12 sports "is for everyone," not just professional athletes like himself. The ad features a wide range of athletes from different ages overcoming obstacles in their own athletic journeys. From a runner to a figure skater, the video shows clips of people pushing themselves.
