Sometimes you see a police officer on the street. It always makes an impression, especially on children. If there’s really something going on, extra officers are often quickly dispatched. If it gets really out of hand, sometimes the army also gets involved. Fortunately, this almost never happens.

Our blood is somewhat similar. If you are healthy, some white blood cells flow through your blood. In case of an infection, or something else nasty, there are many more white blood cells. If it gets really out of hand, special white blood cells come along, the natural killers.

My blood has a significant increase in the number of natural killer cells. It’s as if you see a lot more soldiers walking on the street. They couldn’t find a cause in my case. There is no infection or anything else nasty that the doctors have found. I am fortunately just healthy.

Recently, we discovered that Alan has the same thing. Also a significant increase in his natural killers. It seems to be something genetic. Maybe we are the next step in the slow evolution of humanity, who knows. I think someone took an interest in our slightly different blood makeup, so maybe they will do a few extra tests, and we will find out more in the future.
