Human is a term used for not human beings, but being truthful and kind to yourself and others. As Salman Khan's motto, 'Being Human' is just the opposite the actual word, 'human being'. Everyone is a human being, but it's most important to be a human. A human is someone who can be truthful to himself and others. On the other hand, a human being is a word for a collection of just people. They can be kind or cruel. But a human is someone who will always follow their hearts and be kind.
