I've had a couple of high blood pressure readings at the doctor's office--I've pretty much always gotten white-coat syndrome with new doctors, but this is a doctor I've had for a while, so she was a bit hmmm about it. After tangling with the blood pressure machines at the supermarket (which are free for a reason) I went ahead and bought a home monitor--they're not expensive, and I really wanted to have reliable data. If there's a problem with my blood pressure, I don't want to ignore it and wind up like my brother, but I also don't want to be put on medication just because some doofus almost backed me over in the supermarket's parking lot.
I've been reading up on how to take accurate measurements (do it in the morning before you've had caffeine), plus I've been taking it at various times during the day just to get a sense of what my own patterns are. (At this point, it doesn't look like there's a real problem.)
So after I finally managed to get some writing today, I took my blood pressure. And in spite of the fact that 1. it's the afternoon, and 2. I drank a whole bunch of caffeine to help the writing along, my blood pressure reading was the lowest it's ever been--and I took it twice to make sure!
And, you know, this is what I have been telling people! Like, yes, what I'm doing for the family is very important and meaningful, and yes, there are other enjoyable activities out there--but they're not writing. They're just not. And if you're a writer, there is simply no substitute for the real thing!
