But collagen isn't just for healing boo-boos. It also plays an important role in how skin ages. Gordon explains that collagen is the support structure that gives our skin a firm, young appearance.

Some cars' values rise with age, if they are original cars and not kit cars. '32 Fords are extremely expensive -- if you can even find a real one. The '57 Chevy is another timeless classic that will never go down in value. This collectible also is very difficult to find and can cost upwards of $80,000 to $100,000.ome of the more popular collectible cars that do not lose their worth are 1967-69 Chevrolet Camaros, 1966-72 Chevrolet Novas and 1966-69 Chevelles. Chevrolet put out an SS model on all three of these cars. The SS models are worth a lot more than the plain models.
