On issue of blood pressure....
As we get older, it is perfectly normal for arteries and veins to be less elastic than a teenager. Less flexible arteries means blood pressure will be naturally a bit higher.
If one exercises regularly, it is the best way in my opinion to avoid building of sludge/plaque in arteries. Very difficult for plaque to form if blood is made to move fast regularly. In my own case, I had chest pains after eating a good meal in my late 50’s. Now at age 81 I can eat a prime rib dinner and not even a hint of pain. What changed? I am convinced the regular exercise created new arteries in heart. My resting heart rate is now lower 60’s. In my 50’s age it was about 75.
I have a vibration platform. 10 minutes drops my BP back to normal for several hours. I use it 3 times a day. It has also done wonders for my balance, bone density and muscle tone. I also have an eliptical for daily “walks”, it’s way more fun than a treadmill.
