What secrets lie beneath the deep blue sea? Underworld takes you on a remarkable journey to the bottom of the ocean in a thrilling hunt for ancient ruins that have never been found--until now. In this explosive new work of archaeological detection, bestselling author and renowned explorer Graham Hancock embarks on a captivating underwater voyage to find the ruins of a mythical lost civilization hidden for thousands of years beneath the world's oceans. Guided by cutting-edge science, innovative computer-mapping techniques, and the latest archaeological scholarship, Hancock examines the mystery at the end of the last Ice Age and delivers astonishing revelations that challenge our long-held views about the existence of a sunken universe built on the ocean floor. Filled with exhilarating accounts of his own participation in dives off the coast of Japan, as well as in the Mediterranean, the Atlantic, and the Arabian Sea, we watch as Hancock discovers underwater ruins exactly where the ancient myths say they should be--submerged kingdoms that archaeologists never thought existed. You will be captivated by Underworld, a provocative book that is both a compelling piece of hard evidence for a fascinating forgotten episode in human history and a completely new explanation for the origins of civilization as we know it.Binding Type: Paperback

Good Stuff!
Flavor Name: Mint, Size: Pack of 1 (4 Ounce)
I have been trying different non fluoride toothpaste and I think I have found a winner! This toothpaste leaves my teeth clean and my mouth fresh! The texture is great and I am impressed with the ingredients. The price is a little pricey but you only need a pea size amount. Very easy to use and does not run out of the tube like some non fluorides Ive used. Definitely will buy again!

Flavor Name: Mint, Size: Pack of 1 (4 Ounce)
I love this toothpaste! I have tried several hydroxyappetite pastes and this is by far my favorite. My teeth feel clean, I have zero sensitivity issues anymore and my dental check ups are very good.

Pineapple and papaya
Color: A - Magic Mint (Pack of 3), Color: A - Magic Mint (Pack of 3)
I like it okay. I will use all of it but I am unsure if I will buy it again. It foams very little. I feel like I use more than I do with other pastes/gels. My mouth feels clean without having that too minty/medicinal taste from traditional flouride pastes. It comes out of the tube easy and sticks to my brush. I didn’t know until after I purchased it that there is papaya and pineapple extracts. There IS a photo in the product description that says this and I neglected to click through them all. I have two members in my household that are allergic to those ingredients so I have not had them try it. The only taste is a mild mint though. I think the whitening effects of nanohydroxyapatite pastes is much better than other popular brands that boast “whitening.” My teeth simply look whiter and shiny.
