Just 2 days ago, after bicycling 32 miles a day for 8 months (starting on my 63rd birthday), my doctor took me off Depakote (an anti-seizure medication prescribed for mild-bipolar complicated by suspected ADD) and cut my blood pressure medication in half (It was already a minimal dose), with a view toward taking me off all meds in a couple of months.
Biking has given me a total new lease on life. Two years ago I was in the ER with 185/145 BP, and day before yesterday I was at 104/72. Doc says I have the BP of a teenager. Wants to make me a poster boy for overweight "over-age" people who won't exercise and lose weight. (O, yeah, I'm down 17 pounds and shooting for another 15.) Bicycling is good for what ails you.
