Study after study shows that exercise is the best medicine for virtually everything, the closest thing to a magic health pill that exists. Genetics and luck play a big part too so be prepared for s**t happens. I'm turning 76 and have been active all of my life with skiing, windsurfing, roller hockey, etc. The last 20 years I have been an avid cyclist and also keep up with weights. I just returned from a bike and barge tour in the Netherlands.
In 2020 I was diagnosed with Parkinson's Disease - progressive neurodegeneration, no current cure - as I said, s**t happens. One of the most troubling symptoms about 1/3 of us get is neurogenic orthostatic hypotension. When I stand my blood pressure drops more that 20ml diastolic and systolic. I can usually walk OK but have to be on the lookout for dizziness. Luckily, cycling is a good position for NOH and does not present a problem. On the other hand, I tried a Pickleball for PD group and discovered that jumping around or any sort of running is out of the picture for me. Still, the exercise magic pill seems to help slow the progression of most of my other PD symptoms. I plan to keep cycling until I can't, then maybe a rowing machine?
