More than 4 years have passed since I can last remember being sick, and by sick I mean something like the common cold, the flu, or strep throat. I’m talking about fevers, chills, nausea, congestion, severe coughing, body aching, can’t get out of bed kind of illness. I know this needs to be more than a self congratulatory article, so how will you benefit from my accomplishment? Well, this is also an opportunity for you to do the same. Allow me to briefly explain how my immune system successfully defended me against all invading microorganisms for more than 50 consecutive full moons.
