We can tell you that smoking will make you more prone to lung cancer, try to freak you out with pictures of a bloodied lung and tell you that your testicles will shrivel up into raisins (okay, that last part isn't true), but why bother when a picture is so much better?
To highlight the damage that smoking does to your body, a brilliant website called Tobacco Body in conjunction with the Cancer Society of Finland has launched an interactive experience that shows the difference between a smoker's body and a non-smoker's body.
The design is very slick and you can toggle between left and right arrows to see what it does to you hair, nails, teeth, genitals and skin to name but a few.
The website says: "the skin looks unhealthy because the chemicals in the cigarette smoke make the skin's elastic fibres snap more easily. A weary face is not a popular one: our of the 100 most popular profile pictures in a dating service only two were pictures of smokers."
"Smoking damages the lungs and makes breathing more difficult. The smoker can't run or dive as long as others. When old age hits, there is also the risk of chronic obstructive lung disease."
"Smokers are more likley to get spots. Smoking weakens the skin's blood circulation, which increases the risk of infections."
"Smokers have brittle hair, and they are more likely to go bald and grey than others. Chemicals from tobacco gather in the hair, and cause hairs to break off before they are fully grown."
