The 120/80 benchmark isn't lunacy. Most people in the west have issues with hypertension because that's the direction it goes due to the common risk factors.

If you're at 135/85, and you're middle aged / younger, and your diet and lifestyle aren't already optimized, it's something you should probably care about, not look for the next highest rung on the ladder so that you can celebrate for being below it.

You're completely missing the point. There's a significant amount of people middle aged and younger with numbers something like 125/75. They may have that same blood pressure never change from about 20 years old until their 70s.

Elsewhere they'd be borderline normal, but "in the west" (really just the USA) they're considered stage 1 hypertension and it's anyone's guess what wild nonsense the doctor will tell them once that's in their chart.

It's a total circus. Covering your own ass and screwing the patient over by assuming the worst is not preventative medicine. Overprescribing medication would cause harm if the patient is too naive for their own good despite doing everything else right. Nobody in their right mind should listen to that kind of doctor or take the medication.
