the lifetime risk of hypertension

this study has a cohort size of 1.25 million people - an impressive feat in itself http://www.thelancet.com/journals/lancet/article/PIIS0140-6736(14)60685-1/fulltext this is one of the figures from the paper showing years of life lost per cardiac diagnosis - it seems that the blood pressure ranges to be in are 90-114mmhg ofr systolic and 60-74mmHg of the diastolic - is this surprising?
