Brandon Cohen, of BroBible.com, spent almost 12 hours in 3 inch heels in order to prove that women complain too much. What he found was that the struggle is real. You can watch him wobble in pain as he's filmed throughout his workday at the end of the article.
Halfway through the experiment, he made the statement that "I wanna kill everybody" due to the pain.
Cohen also said that it was the "worst day" of his life. Next time you see someone wearing heels and she's giving you a hard time, just know that her heels are giving her an even harder time.
