When a person attempts to move, nerve signals are sent from the brain to the muscles via motoneuron, moving the musculoskeletal system as a consequence. At this moment, very weak biosignals can be detected on the surface of the skin. HAL catches these signals through a sensor attached on the skin of the wearer. Based on the signals obtained, the power unit is controlled to wearer’s daily activities.

quote: People get injuries when they STOP taking steroids. Notice what happened to Barry Bonds? Or Jason Giambi? Or Clemens? When they were juicing like madmen, they were on the field, but soon after the crackdown on steroids, they were spending time on the disabled list. Same with Palmeiro. Steroids have a tendency to make more fluid retain around the joints, which allows them to move with less friction. Once you stop, they dry up a bit, and then injuries can happen.
