The risk of death for smokers who puff 10 cigarettes—half a pack—a day is still double that of nonsmokers, says a study of 200,000-plus Aussies 45 and older. And regular smokers can triple their death risk. “People don’t realize how damaging even light smoking [Half a pack, “light”? Oh, Australia.] is for your health, for cancer, heart disease, lung disease, and many other conditions,” says study co-author Freddy Sitas. If you’re on the road to quitting, great—just keep it up till the ashtray’s in the rearview mirror.
