Physical Fitness and Longevity

Maintaining physical fitness not only improves work performance but also increases longevity. Living a longer life enables individuals to have more years of contribution and mentoring, which are highly impactful. The most significant impact comes from guiding and mentoring others, akin to characters like Gandalf or Yoda, which typically occurs later in life. Contrary to common belief, consistent walking, rather than daily intense workouts, weightlifting, or cardio, is the most effective way to increase lifespan.
