What are the chances of developing hypertension?

I have blood pressure of around 123/80, I am 5'10" 183 lbs, which puts me at overweight, I have a 32 inch waistline, "pair shape" body. Blood pressure in the range of 120-129/80-89 is now considered bad and prehypertension. One article I read said, that with a blood pressure like this I am 4 times more likely to have a stroke or a heart attack than the average people in my age group, I am 22.
