Man cannot live by bread alone (можно небольшой рассказ о этой пословице на англ)

The difference between human and animal is people have developed consciousness. Our life activities includes not only meal but also getting knowledges and skills, entertainment and activity for making our life better and more interesting. We are interested in philosophy, mathematics, arts, music, nature life. This all includes non-material things which we cannot use as meal. It is a feed minds.

feed minds - пища для ума.
