A friend I work with has one on those automatic testers, you know the ones, you strap it around your wrist and it pumps up with a little motor. We tested all of us in the office and mine came out as 120/80, we did it a couple of times to get an average, and it was the same each time. We tried a guy who has diabetes and his was really high. I guess mine is ok for someone of my age. I try to eat healthy, although I am not as fit as I could be.
So what are the main signs of high or low pressure? can you tell by just looking at someone?
