Our surgery sends out somewhat clunky text messages of a similar format, though they've yet to ask about my blood pressure. It's almost like they don't care. They probably don't, I did gripe about their lack of bicycle parking the last time (and the time before that, and the time before that) I was there. My blood pressure might have gone up then.
Today I don't know what is. I don't like having my blood pressure taken, I always think the cuff will sever my arm and it'll end up the floor and the doctor saying well, I've not seen that happen before. Then it'll grow back like a lizard tail. And I mean a real lizard tail and the doctor will say (again) well, I've not seen that happen before. And then I'll end up as a case report in the BMJ.
Generally, I take this as good enough reason not to visit the doctor unless it's genuinely likely that something will fall off.
