According to LifeScript.comhere are some bad habits that make you look old:

You're too skinny -- Loss of facial fat causes sagging, aged appearance.

Rubbing your eyes -- Pulling, tugging and rubbing on delicate skin around the eyes can cause darkness. And, because pigment changes as you age, this can add years to your appearance.

Not sleeping -- At night, skin goes into a renewal state. It repairs itself and there's a difference in its pH and circulation so anti-aging products penetrate better.

Sleeping on your side -- Believe it or not, pressing your face into the pillow eight hours a night for years can break down skin and cause wrinkles.

Sipping out of a straw -- Over the long-term, pursing your lips to sip out of a straw or smoke cigarettes causes extra wrinkles around the mouth.

Stressing out 24/7 -- If you're chronically worried, your body is pumping out stress hormones non-stop. Cortisol, the major stress hormone, breaks down collagen, which leads to sagging skin and wrinkles

Using soap -- Soap often contains harsh detergents that strip skin of natural oils, so make sure to wash up with a soap-free cleanser and then apply moisturizer to damp skin.
