OFSO has a valid point we are all different what is normal and harmless for one isn't for another yet we are all treated the same.
i had high readings in my 20s and have past 20 plus medicals since.
second point Doctors love to measure things and something like BP which is NOT constant, can vary during the day, month year etc, how high your heart rate is, how stressed you are etc maybe not as indicative as some make out!
I also find the scale is conducive to something racy! fast.
" You loose your licence if caught doing over the ton
Much better for your BP if the Doc says " your BP is 2.6 over 1.9
why the 170/100? that itself is a racy sounding scale! itself enough to raise the old BP
