LeBron James' exceptional longevity and sustained performance in the NBA at nearly 40 years old is attributed to his rigorous work ethic and dedication to maintaining peak physical condition. Former teammates like Shane Battier and Greg Oden have marveled at his commitment, noting his extensive routines and significant financial investment in his body. James continues to achieve high stats, averaging over 25 points, 8 assists, and 7 rebounds per game last season, and making a significant impact at the 2024 Paris Olympics. His work ethic is often compared to other legends like Michael Jordan and Kobe Bryant, who also exemplified relentless dedication and competitive spirit throughout their careers. James' ability to stay at the top of his game is seen as a testament to his focus on both physical and mental aspects of excellence.
