I work in QC. I perform in musicals and plays, play banjo and guitar, write a blog, practice kung fu, and sing in a choir.
And yes. I am a short guy.
If anyone ever tells you that you can't do something physically just because of your height, I'd take a look at this guy. At 5'1" he dominated the American Ninja Warrior course, and became the shortest man in Ninja Warrior history to take on the Warped Wall. As you hear the announcer says: "Height is only a number."
