different countries have different standards for what constitutes high blood pressure. variations are normal too as mentioned above. and yeah, i wouldn't trust a drugstore machine with my bp read either. think those things are calibrated on any regular basis?
just keep doing the right stuff. it will be fine.
As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.
