Today, and for a while, I am a subject.

I am not a Brit. They--to my way of thinking--would probably have an image such as this when they hear of a person's identity being referred to as a subject. To those who might not quite grasp the context, I am going to add the descriptive caption (with some minor editing). "1953, historical, female workers at drapery company, Hepworths of Leeds, England, UK, sitting at work benches with sewing machines. The factory floor is decorated with bunting and flags celebrating the coronation Queen Elizabeth to the British throne. Providence Works on Clay Pit Lane, a clothing company, was the home of Joseph Hepworth and Son. It was established in 1865 and by 1905 it had 143 shops. Later in the century, Hepworths became Next."

So no, I am not a subject of HRM. My identity as a subject refers to my being a person in a random study on the measurement of blood pressure for data collection.
Over the years, I have done numerous studies. Most of them seem to be online ones such as e-rewards dot com. And more often than not, I find myself going through a lengthy question-and-answer sequence of inappropriate inquisition only to be told that my answers do not qualify me for the study. To which I respond to the computer with a(n) heartfelt, "Well, f**k you very much, as well !"
I don't put a tremendous amount of stock in some of these home surveys. I think of myself as an outlier. I weigh and measure the foods I eat. I awaken each weekday to the sound of an alarm that is placed at the far end of the room so that I am ensured I will rise and walk to the device in order to stifle the annoying tone. I eat meals over the sink while standing. I am not bothered by cupboard doors that do not close, shopping bags that aren't neatly folded, or shoes that aren't placed on a rack somewhere.
On the plus side, I brush my teeth four to six times a day which seems to raise many on eyebrow on those who learn of this. "You brush your teeth BEFORE you eat breakfast?" a college friend of mine had one time asked. "Yes," I replied, "you don't?" "No! Why? You're just going to dirty them with food and you will have to brush them again."
I rolled my eyes. For this is a person who scrubs the tops and bottoms of bowls and plates with the same elbow grease as if the meals were consumed on china that is turned upside down during the meal.
"Before you start a meal, you are supposed to wash your hands. You are also supposed to wash your hands when you have finished the meal, as well. The same goes for your teeth and mouth. When you have been sleeping for however many hours you have been in dream land, your oral cavity is colonizing a(n) whole host of bacteria, slime, and pathogens. Calculus, tartar, or whatever you call build on your teeth. Don't even get me started on the goings-on of your gums, cheeks, and that movable organ in the floor of your mouth!"
In any event, I like to think of myself as being a small contributor to(wards) the furtherance of good science. And financial compensation merely sweetens the pot.
And who doesn't love sweetened pot?
