September 29th is National Coffee Day and caffeine-lovers everywhere are raising their mugs in honor of their favorite beverage.

This miraculous drink is just the thing to motivate the body out of bed and get it through the morning routine. It is the perfect fit whether it is hot, iced, frozen, sugared creamed or black as the night.

Take a sip and learn something new about the world of coffee.

1. You can get your hands on some free (or cheap) coffee today.

National Coffee Day is essentially a made-up marketing holiday, but that doesn't mean you can't enjoy the benefits. Restaurant chains are using coffee deals to rope in customers all day today. New Englanders love their DD, and they are offering a free medium cup of Dunkin’ Donuts hot Dark Roast Coffee, with a limit of one per guest. McDonald’s is continuing to offer a complimentary small coffee in the morning until the end of the day today. There are plenty more deals to be found.

 2. How much caffeine is in my coffee?

The amount of buzz you'll be getting from your coffee depends and the brand and how it is prepared. According to Caffeine Informer, a normal cup of brewed coffee contains 20.4 mg of caffeine per fl. oz on average. Espresso coffee contains 51.3 mg per fl. oz, while instant only contains 7.1.

3. Pumped up goats may have led to the discovery of coffee.

Legend has it that the discovery of the benefits of coffee beans dates back centuries ago. A man named Kaldi of the Ethiopian highlands noticed that goats would become much more active after eating berries from a  certain tree. He brought that discovery to a local monastery and word of the energizing effects of coffee beans soon spread across the word.

4. It could help you live a longer, coffee-filled life.

Drinking a lot of coffee has been found to increase life expectancy, according a study by researchers from the National Cancer Institute and AARP. They found that those who drank caffeinated or decaffeinated coffee were less likely to die from "heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections." Of course, these findings are subject to scrutiny, but it doesn't hurt to think that coffee mug is the ticket to a long life.

5. We drink a lot of it, but don't grow it.

With the exception of Hawaii and Puerto Rico, no coffee is grown in the United States or its territories, according to CoffeeFacts.com. It is grown in over 53 countries worldwide, with most of it grown on Brazil's over 3,970 million coffee trees.
