Okay, when i said that smoking despite knowing the health risks was stupid, i didn't mean that concept was only applicable to smokers, i agree, doing anything whilst knowing it could kill you, is stupid. That being said, i don't mean crawl in a hole and never take any risks. All i mean is there are many things you're reffering to, such as drinking, eating fatty foods, exposing your body to the sun etc, which can be done in a reasonably healthy manner, with minimum associated risks, when done in moderation, like i said. There is no safe or moderate way you can smoke without it causing damage to your health. That is a proven scientific fact, hence why these things aren't treated the same as smoking, generally, they're less of a health risk. However, lately, there are just as many campaigns about binge drinking, skin cancer and obesity etc as there are about smoking, it's not as if they're completely disregarded as a health problem.
