Veins: Veins are small elastic colorless tubes or blood vessels that carry blood circulating around the body from the various organs back to the heart. Paint: Paint has been around since prehistoric times used by our homo sapiens ancestors thousands of years ago and moving forward humans as a species have been using paint in one form or the other ever since. Teeth: Teeth are the small white calcified structures that are found in the mouths of most vertebrates. Teeth are primarily used for chewing and breaking down food for digestion. Most carnivorous animals however have a sharper type of teeth that are also utilized for hunting and self-defense. Sneakers: Sneakers or rubber shoes have become commonplace in today's modern world.

Glue: A glue or adhesive is a substance that is used to bond different surfaces or quite simply, it is used to stick things together. The first types of glue were naturally occurring adhesives like tar, beeswax, egg whites, plant gum and animal glue. These were used by our ancestors for thousands of years.
