Followers of Breatharianism believe that humans can live without food or water. Wiley Brooks, founder of the Breatharian Institute of America, even claims to have survived mainly on a diet of fresh air for the past 30 years.

It’s not clear what he counts as fresh air — in 1983 he was spotted leaving a Santa Cruz 7-Eleven with a Slurpee, a hot dog and a box of Twinkies.
