Body language, the mind and behaviour.
So, I came across this TED Talks recently ( Amy Cuddy: Your body language shapes who you are - YouTube ), and it speaks of the hormonal changes that come from one's posture and pose have on their mind, hormones, and overall behavior. Sometimes, I think the mindset is a very important part to the Primal Blueprint that often gets overlooked in comparison to the food and exercise, but just my opinion.
So, what do you all think about this? Does it sound credible?
