I find it crazy that there is a bug that actually exists in this world, which can penetrate the skin with the smallest pin shaped needle, and suck blood from within the body. And this tiny bug can be squished and killed by your two smallest fingers.
A mosquito acts as a syringe in a way, but why is it that disease only spread from shared needles, and not shared mosquitos. Or do they? To wonder if a person with full blown AIDS was to get "bit" by a mosquito, and then that same mosquito found its way towards you to deliver a second "bite." Would this spread the disease as if you were to share a needle with someone that has AIDS? That's about as rational as reality gets.
