I'm about to turn 62 and the only prescriptions I take are 5mg Taldalafil that I have been taking ever since I had prostate cancer surgery, and 5 mg Finseteride that I choose to take to keep my hair growing and healthy.
If push ever came to shove - in terms of my health - I could do away with both of them and still be just fine.
HOWEVER, I also take a number of non-prescription all-natural supplements. Vitamin C, vitamin B complex, calcium/magnesium, a multivitamin, and a Costco tumeric/black pepper capsule twice a day.
AFAIAC the supplements I take probably do more for my general health than the prescriptions. JMO...
