Jim Thompson emphasizes the importance of taking care of

one's physical body, particularly feet and legs, in physically demanding work

environments like pulp and paper mills. The author recounts a personal anecdote

to illustrate the potential hazards and the need for proper footwear and

preparation. The text also advocates for proactive self-care, including regular

check-ups for knees and hips, maintaining a healthy weight, and considering

exercises like Pilates or strength training to support overall body health. It

highlights that, unlike mechanical transportation which can be repaired, the

human body has limited repair options and needs to be maintained for a

lifetime.
