Yeah, that's another thing. Hypertension can affect anyone, anytime, especially if you have a family history of it (I do, both sides... everyone.) I became hypertensive at 25 or so. Healthy otherwise. My doc said she wasn't surprised. She said with such a strong history of it in my family, it was just a matter of when, not if.
I went from 155/100 down to the normal range 120/80 and lower until you faint when you get up... then it's too low.
Lisinopril worked a charm on me.
