I don’t look like it, but my health kinda stinks. My immune system is crap. I’ll briefly explain a little about the immune system. There are four immunoglobulins, which are like the ammunition that white blood cells make to kill viruses and diseases. If you’re a medical doctor reading thing and I’ve got it wrong or there’s more too it, feel free to chime in. Anyway, these munitions, these immunoglobulins have specific tasks in specific areas of your body. They are called M, G, A, D, and E. I’m deficient in the first three.
