Three friends met for lunch. One observes another drinking water between bites of her sandwich. This person got full at once.
One friend remarked about the one who got full first, "She eats to live we live to eat."
Does a person eat by the time clock? Does a person eat because she or he is hungry?
A person eats for nourishment. You should eat only 80% of your stomach capacity.
Some eat to live!
Some live to eat!
