Sorry to hear that. High blood pressure runs in my mothers side of the family but I've always been lucky with that, until about 6 months ago when I found out I have slightly high blood pressure now I think about it all the time because its likely going to rise. Shitty thing is I'm not in bad health or over weight (maybe 10-15 pounds) but its genetics man. You can't run from genetics.
Some people hit the lotto on that stuff. My wife's grandmother lived 101 years. She was born in 1911 and died in 2012. So that was just a few years ago that she passed and when she was born her family had a horse and carriage. It was the weirdest thing I've ever seen too. It wasn't like she had a heart attack or stroke, she just wound down like a watch, got into a bed, and passed away. Cause of death, old age. How often do you see something like that? Blew me away.
