How do I cope with a body worn down by years of physical work?

You know the flow of goods in your bones, better than any system on a screen. That knowledge came from years of real physical work, and now your body is showing the cost of it. Reckoning with that is hard, especially when the work was also a source of pride. Be honest with yourself about what is happening, without shame. A body that is worn is not a body that failed. It is a body that did the labor, that carried and lifted and stood through years most people never see. The ache is a receipt for real work. But it is also a signal worth heeding, not pushing past. Start protecting the body that has carried you. Take the help you have earned the right to ask for, lighter methods, better tools, tasks shared with others, and consider how your deep knowledge could shift toward teaching and directing rather than lifting. Your value was never only in your back. It is in everything you learned. Let that carry more of the load now.
