Health is the soul that animates all the enjoyments of life, which fade and are tasteless without it.Lucius Annaeus Seneca

In theory one is aware that the earth revolves, but in practice one does not perceive it, the ground upon which one treads seems not to move, and one can live undisturbed. So it is with Time in one's life.Marcel Proust
