Do a little nothing for your health

In most cases, staying healthy requires that you do something. Work out, watch what you eat, etc. All said, it's clear that it's much easier to be unhealthy than it is to be healthy. But one of the few cases when not doing something is actually better for you is smoking cigarettes.

There have been numerous studies on the ill effects that smoking has on the human body. From your lungs to your skin, smoking will do a number on you. And, in some men, it can even cause erectile dysfunction.

Now, as for not doing something -- that is, not smoking -- the effects are almost immediate. Within 20 minutes of quitting, your heart rate and blood pressure will lower. After two weeks, your circulation will improve and your lungs become more functional. What do you say? Is it time to quit?
