Belt is a flexible band or strap, typically made of leather or heavy cloth, and worn around the waist. A belt supports trousers or other articles of clothing, and it serves for style and decoration. Belts have been documented for male clothing since the Bronze Age. Both sexes used them off and on, depending on the current fashion, but it was a rarity in female fashion with the exception of the early Middle Ages Timing Belt Many of today's engines use timing belts, but not all. Some engines still use a timing chain. Now, we all know that belts and buckles for jeans or other pants are a totally utilitarian object, the sole purpose of which is to keep your pants up. Well, I think there is much more to belts and buckles than that. Just think of where they are used. You're adding a horizontal line right at your mid section! Imagine the potential that they have to add or subtract from the composition that you're creating.
