WHY does a cramp occur? 
 

Cramps are especially common in the muscles of the foot, fingers and calves. Physiologically, a cramp is an abrupt contraction and spasm of muscles caused by circulatory disorders or physical exertion. 
 
A frequent cause of a cramp may be an abortive movement or monotonous repetitive motion. Such cramps develop in people typing a lot on a PC or playing with a computer mouse, working on their feet, or exercising intensively. 
 
Leg cramps are frequently caused by a lack of calcium and potassium salts in the body. This often occurs with intense exercise, taking diuretics, and dehydration.

The High-Skilled Workers

The High-Skilled Workers   Brynjolfsson and McAfee call the group personified by Nate Silver the “high-skilled”workers. Advances such as robotics and voice recognition are automating many low- skilled positions, but as these economists emphasize, “other technologies like data visualization, analytics, high speed communications, and rapid prototyping have augmented the contributions of more abstract and data-driven reasoning, increasing the values of these jobs.” In other words, those with the oracular ability to work with and tease valuable results out of increasingly complex machines will thrive. Tyler Cowen summarizes this reality more bluntly: “The key question will be: are you good at working with intelligent machines or not?” Nate Silver, of course, with his comfort in feeding data into large databases, then siphoning it out into his mysterious Monte Carlo simulations, is the epitome of the high-skilled worker. Intelligent machines are not an obstacle to Silver’s success, but ...
