Simple acts of picking up a water glass or turning a handle are the product of multi-layered cognitive plans and sophisticated neural computations. A thumb-up posture would have probably allowed the guard to have greater power and more control. Healthcare professionals may find work relevant for informing medical diagnosis and rehabilitation. Regulators, managers, and engineers may benefit from the work insofar as it may inform the design of skill-training systems and safer and more efficient set ups for work, transport, and play. Presumably, the waiter used a thumb-down grasp to allow him to complete the task using postures that were comfortable and easy to control. All the participants were right-handed, but half were instructed to use their right hand, while the other half were instructed to use their left hand. To accomplish this, they sometimes adopted extreme arm positions at the starts of the rotations.
