IMO, there is a big genetic component to it. I have high blood pressure(although not really high - it averaged 145/98 before meds) and yet I have no risk factors other than family history. Even when I was in top cardiovascular shape it was high.
After about 6 months of monitoring and doing everything I could to get it down on it's own, I had to go on meds (Micardis plus) as it just wouldn't budge down consistently.
