WBC . . . . . . . 3.2 L (3.6-10.6)
So, apparently the healthy range is 3.6-10.6, but I only have a 3.2. The doctor noted that this would leave me "susceptible to infection and colds". Well, since I haven't had a random infection or cold in... almost two years, this connection does not seem to be accurate. Yes, admittedly I've been mildly sick a couple times in the past couple years, but I know exactly why it happened. And even so, it wasn't anything like how I used to get sick, which was more often and much worse. Things just don't add up to doc's observation.
So, consider a hypothetical population entirely of lethargic and lazy people only. Their high heart rate would be considered "normal". And if one of these lethargic people had a lower heart rate than that standard, it would not be a good thing like in the case of an athlete. Indeed, for a sloth that lower heart rate would probably mean that something was wrong.
Then, lets say one tiny percentage of this previously lethargic population becomes active. The active people would become healthier and develop a lower heart rate, and the doctor would probably tell them that it is dangerously low! So what should they do? Either 1) take some drugs, or 2) go back to being lethargic. Both of these actions would get their numbers back to "normal", but neither of which is a necessary or correct solution!!
That's how I feel about my low WBC. I'm being compared to Joe Shmoe who eats a Standard American Diet (SAD), stressing his body on a regular basis and forcing it to react with in a defensive manner. However my body is clean, what does it need a bunch of extra white blood cells for? That's why I'm not getting sick, contrary to doc's prediction.
I could very well be wrong in this logic, since I don't really know much about human biology other than the simple cause-and-effect relationships of my actions and how those actions make me feel. But I do know that I'm not getting sick and I feel great. If you know something that I don't, leave a comment.
