That's a very traditional lifestyle, and they get up early in the morning, go to bed early, because they have worked hard their whole life, mostly with their hands, very often had a very small family business, a small farm, a shop, or like Mr. B, he was a farmhand.
Ese es un estilo muy tradicional, en el que se levantan temprano y se acuestan temprano, porque han trabajado duro toda  la vida, mayormente con las manos. En muchos casos tuvieron  un pequeño negocio familiar, una pequeña granja, una tienda, o como el Sr. B.,  que trabajaba en el campo.
