Immobility is a very bad thing for muscles.

Immobility is bad for everything, for a brain first of all. And for heart. When body moving and muscles contracting, they pumping blood back to the heart, making its work more effective. Muscles are the body's chemical factories producing countless adaptogenes for happy living. This is so called condition of muscle joy. Do you think all of this can be replaced by something artificial and unnatural from outside? By prescription or not...
