where ln is the natural logarithm, Nf/No is the percent of carbon-14 in the sample compared to the amount in living tissue, and t1/2 is the half-life of carbon-14 (5,700 years). t = 18,940 years old. Because the half-life of carbon-14 is 5,700 years, it is only reliable for dating objects up to about 60,000 years old. However, the principle of carbon-14 dating applies to other isotopes as well. Potassium-40 is another radioactive element naturally found in your body and has a half-life of 1.3 billion years.
Yeah, I'm not its biggest fan either, but when it comes to collagen, garlic is the best to restore collagen in your skin naturally.

The Causes And Effects Of Collagen Loss By NewBeauty Staff | July 12, 2010 Collagen is a tough, almost rubbery protein that's created by cells called fibroblasts. Packed together as bundles, fibrous bands of collagen serve as the main support system of the dermis, the deepest layer of skin. Collagen gives skin its strength, and it makes skin firm and flexible with the help of elastin. Collagen is essential for young-looking skin because it gives structure to its cells. When collagen levels becomes depleted, the skin has little internal support, causing it to sag and contributing to wrinkles. Furthermore, when there is ample collagen in the skin, it's strong and more resistant to the effects of weight gain, so a lack of it can lead to a greater risk of stretch marks. Around age 35, collagen production naturally begins to taper off, and the quality of the collagen diminishes.
