Keep healthy-looking skin.

This tip won’t help you live longer, but as long as you’re working toward lengthening your life span, you might as well look good while doing it.  Amy Wechsler, dermatologist, psychiatrist, and author of The Mind-Beauty Connection: 9 Days to Reverse Stress Aging and Reveal More Youthful, Beautiful Skin, explains that retinoids are wrinkle reducers. There are certain beauty creams that contain retinoids, but they can also be found in food, such as carrots. Eating carrots helps balance the pH of the skin’s surface, making it slightly acidic. That’s good news, because slightly acidic skin fends off bacterial invaders. In addition, dark chocolate improves skin’s texture, thickness, hydration, and blood flow.
