I’ve never actually researched this hypothesis because I’m sold on my assumption that yawning’s contagiousness is mother nature’s method of regulating sleeping patterns among species, considering they naturally socialize and would pass that wildfire of yawning amongst each other.
Anyway, I can yawn on command and I don’t think everyone can do that.
So pretty much I harness control over all of human kind, rendering those within my yawn contracting radius defenseless to unstoppable sleepiness. Which will make stealing their Nutella easier. Pretty much I’m an X-Man. And I’m totally gonna hit it with Storm. I also intend to persuade Wolverine into whittling me a wooden flute.
