Humans are the animals that manufacture weakness. We take wolves and we make them into dogs. We take buffalo and we make them into cows. We take stallions and we make them into geldings. We make things weak so that we may use them.
Our modern sedentary life is one for which we have not been designed and for which, at least biologically, we are poorly equipped. It is a common misconception – pervasive and tenacious, but a misconception nonetheless – that arses are made for sitting on. It seems, instead, they are made for running.
