Much to the delight of my inner hippie, I’m going through a series of yoga classes about the chakras. After a class about the third chakra (root of our power, determination, drive, etc.), my boyfriend had us watch this TED Talk about the science behind body language and how “standing in a posture of confidence, even when we don’t feel confident, can affect testosterone and cortisol levels in the brain, and might even have an impact on our chances for success.”

You may have to go take a class about the third chakra yourself to really get the connection, but learning about the hippie ways of having power and then getting tips for feeling powerful that are backed by science was (wait for it)….pretty powerful.
