Natural selection operates impartially and without mercy; weakness and lacking the ability to adapt or overcome is an evolutionary dead-end. Only the strong survive. A harsh climate or hostile environment naturally produces a tougher and hardier creature; consequently, the weaker die off at a higher rate.”
This is from a pdf book entitled Brain Over Brawn by Clint Cornelius, and can be found here: http://brainoverbrawn.com/. It’s a free download, and so far (I’m on chapter 4 currently) I’m finding the thought’s and perspective in line with my own. Sound, logical, and simple to understand. If you CrossFit, this book is for you. If you train in Krav Maga, this book is for you. If you’re an athlete, this book is for you. If you want to be healthier, and fitter, this book is for you.
Thank you Kieran for introducing me to this book.
