I've been an active walker, walking 4 miles a day 6 days a week. I turned 87 in June and everyone (until recent) have never beleived me when I tell him my age! In 2019 I had sciatic? nerve problems and was unable to walk without pain for about 5 months. I've used an anti-gravity machine since my early 30's but never had a back problem even tho' doctors don't recommend anyone using them because of high blood pressure problems that might ensue. Nevertheless, I bought a new one at 83 and within 5 days no more sciatic problems. When I returned to walking I had minor heart discomfort. Upon testing one of my heart arteries was becoming clogged up and required a stent. I agreed to being a part of a study that took patients off of blood thinners after 6 months (I didn't know any better). Result was the stent became clogged after only 4 years - which was this year. Discomfort again resulted in the original stent being pushed back with another on top of it, but this time the hospital failed to prescribe a blood thinner along with other meds. Result was within 4 days I had a heart attack as the stent had immediately clogged. Again there was another stent put on top of the other 2. I was diagnosed years ago with a skipped heart beat and was told it wasn't unusual and it needed not be treated. My cardiologist this time recommended I needed a pacemaker which was installed. Now I had to deal with lightheadedness, tiredness and unsteady walking. A month and a half after dealing with this, while standing in the bathroom, fireworks in my head caused me to fall to the floor and crack my femur which required a pin placement. Following a walker and cane I am now able to walk gingerly without either after a little over 3 months. Following physical therapy with the help of my wife, I do exercises for a half hour every day. Upon telling my story, people have recommended I sue the hospital that did not prescribe the blood thinner. I maintain that installing the pacemaker was a big mistake and has done more harm than good!!!!!
