Body Language Tip: Chin Up! (Shark by way of BG)

From Shark by way of Lifestyle with BG:

Beta males hold their chins down to protect their throats in nature. However we evolved, you don't need to protect your throat! Expose your throat and lift your chin up. Showing your throat is alpha!!

As BG says, thinking of it this way seems much easier than to just think of keeping your chin up.
