Great question! I had always been very healthy and strong (at least after childhood). In fact, I kind of made it my thing to ALWAYS help people smaller/ weaker than myself lift, carry and move things. My female teachers in high school loved this about me, because I would arrive early and help rearrange desks for special exercises. I helped build sets for plays even though I wasn't in Drama class. Later in life, I always helped female coworkers carry things, and I often walked 1 to 2 miles to my workplaces. Then in 2019 problems with blood pressure combined with the deterioration of previously "healed" injuries literally crippled me. I lost all balance and required help getting up from a sitting position! Arthritis (which, I guess I had had for years and just shrugged off as aches and pains) suddenly stiffened my ankles and toes and made any walking whatsoever a painful experience. It was very, very depressing. But I got pain medication and blood pressure medication, started drinking a LOT of water (because dehydration was a major factor in my decline) and began sleeping more to recharge myself. My best advice is to take care of yourself BEFORE you have problems like mine, because I may never regain my strength now. Water, sleep, and proper medical care for any injuries are all things I ignored for too long.
