There are always more wars going on than we know of every given day. Whether they are tribal wars in Africa or territorial wars in the Middle East, religious wars in Asia or drug wars in South America if you live in a country that is not currently at war with someone, feel very fortunate. The idea is to wear purple today showing your support for peace, it really is the very least you can do.
How to celebrate – Actively find some way to help those at war. Study where they are wars and police actions in the world today. Enjoy the peace in your country.
