take a look of ourselves or the people around us. When tribal villagers living
in deprived remote areas suffer from blurred eyesight, hard of hearing, toothless
mouth or crippled movements, we are supported with artificial lenses, hearing
aids, dentures and prostheses. We can perform daily activities such as reading,
eating, walking or dressing nearly as well as when we are young. These put
meaning to a long life.
