Making a cup of tea, going for a jog or writing an email, are physical actions and movements driven by the early development of motor skills that are essential to everyday life.  

Marlene Bönstrup led a research team based in the United States of America and Israel, who investigated whether seconds of rest can boost the brain's memory of fine motor tasks, using data sampled from online crowdsourcing. Over a number of trials, a total of 951 participants had been tested on whether they could finger tap out a predefined sequence at certain speeds. The success of the individuals performances was measured following alternating sessions of practice and rest.
