Heredity...black people generally have higher blood pressure, hypertension, and diabetes. The minute my bloid pressure shot up , i got on track early. Not going to fuck around with shit like that
It's not "hereditary". Blacks and most ethnic minorities have a predisposition to these conditions if they become over weight.
In short your high BP is cos you're fat.
Do some grip strength exercises, power crushers, just squeeze and hold for like 3 minutes a day. It's a very easy way to lower your BP.
