I am 61, in my mind I still split wood with a maul and wrestle bears but in truth I have significant arthritis in my spine, hips, knees, hands, oh you get it, everywhere. Have to use a cane to get around and type one handed. My mind is still young but my body is not. Cant' stand the pounding of a dozer anymore but still love/hate the things. Most days are one day of work and a couple of days to recoup.
I still have two tractors and an RTV900 used daily to get me around and a ZD mower. The tractors are a necessity lifting, loading, tilling, hauling and other uses to make things easier for me. Without them I couldn't get much done. Maintenance can pose a problem sometimes getting down on the floor to work on equipment is difficult, getting back up is harder. I have hung some straps at various places in my shop to allow me to pull myself up and this helps. Wife said maybe I should give up my equipment, I will when they bury me. Planing on my next tractor, bigger, more loader lift capacity and a heated /ac cab with an air ride seat. I am not handicapped just physically challenged, but I can still hold and love my grand babies. The pain lets me know I am still alive and that beats the alternative, I still have much to learn and live for.
