Son I've been a respiratory therapist for 10 years, I have a damb good understanding of the respiratory system, you tried to clown and sounded pretty ignorant, I never said we were perfect, but our "design" is as close as it can probably get when you think of how our bodies function, being that is not perfect, things happen and yes PEOPLE CHOKE! But you know how many people of all ages are in te world eating and talking and breathing all at the same time and going about it involuntarily!?...like legit with little to no effort....the nerve of you to downplay human functions and dumbing it down to a level where you think "we eat and breath through the same hole"
