Don t smoke

If you re a smoker, make a concerted effort to quit smoking as soon as you can (easier said than done, eh?). It s one of the worst things you can do if you re trying to avoid looking old. It makes your lips thinner, your skin dryer and more wrinkly, and dull and your hair and nails discolored. As well as this, quitting will make you much more healthy and less likely to get a serious disease in the future.
