Indeed, why can't we tolerate a higher value?

In fact, many doctors worked extensively on this subject and found that above the value of 14/9, the risk for the cardiovascular system is significant. These studies required several thousands patients, whose age varied between 18 and 85 years. On average, the duration of these studies varied from 5 to 20 years.

We know that the higher the blood pressure value, the more significant the cardiovascular risk becomes, testified to this study carried out by an American insurance company in the Sixties:
