Hand power
Abstract
Labor created man. Labor is produced by determining a task mentally by the brain followed by accomplishing the task physically, mostly with the hands and wrists. The thought is material; it is created by physico-chemical processes in brain cells. At the everyday level, materialization of thoughts most often occurs by the transformation of molecular processes in the brain into movements of the hands. Therefore, dynamic characteristics of the hands are an important indicator of the cognitive and motor human health.
