Maybe they're right. I've been seen by 5 or 6 doctors who all agree I have PD. Two say it's probably PD and MS. Last night while moving the scooter into the garage it fell over with my foot trapped between the kickstand and floor. My wife is an hour away so not available to help. It fell as I was trying to balance it to bleed the brakes. So I was trapped with no way of getting help. I flashed on the guy in Utah who cut off his arm when it got trapped under a boulder, I had a pocket knife and was able to cut the shoe laces, Then it took a while but I was able to wriggle my foot out of the shoe and crawl out from under.
I start physical therapy for balance issues on Monday. This morning I have two purple toes but no serious pain. I'll be on the treadmill for a couple of hours if the purple toes allow.
I'm reading Spark, the new science of running and the brain. It says running stimulates BDNF: Brain derived neurotrophic factor, Which is the spark that heals the brain. It recommends running at 70% of max heart rate for an hour followed by reading or studying. Studies say at that point the brain has been primed to absorb and retain new information. If running at 90% of max no retention happens because the body is shifting blood to the muscles and unable to grow the brain.
