...Every nutrition doctor I visit has a bit of a panic attack when they see my near literal bean-pole physique, thinking there is no way in heck that could be healthy for me, but hey, somehow I am anyway......and I have, for a couple of those doctors practically ordered me to gain weight...to no avail ...
Because of this, I believe regular ol' penicillin is no longer as effective as it once was when it was first discovered...
