Input the blood pressure. Normal blood pressure is considered
a healthy level if the "top number" (systolic) is lower than 120 mmHg
and the "bottom number" (diastolic) is lower than 80 mmHg. If the
systolic
blood pressure is greater than 130 mmHg, or the criteria of Stage 1
hypertension or worse is met, the study shows an increased risk of
all-cause mortality.
To learn more about how high blood pressure may lower your life
expectancy, check this report,
High Blood Pressure: Prognosis and Life Expectancy, and this
academic study about the association of hypertension and healthy
longevity, available at
