"Catch Health Online" - a book by the youngest academician of the Russian Academy of Sciences Andrei Lisitsa and journalist Elena Savchuk - talks about the increasingly popular term "health saving," a way of thinking that assumes that we should all take responsibility for our health, and not shift it to the state, medicine and doctors. A person is the manager of his own health, taking care of him and managing him, including with the help of network health-saving technologies available in a smartphone to each of us.
