Just a small protest that the Polio vaccine is highly overrated. π 
I agree. The ones that I think are actually transformational are making fire, farming, writing, and Bitcoin.
i'm pretty sure the polio part of the DPT triple antigen, that i got when i was 5 years old, gave me celiac. i didn't have issues with my intestines before that, and have been plagued with it ever since. polio is a disease that primarily interacts with the intestines.
