And it is this: this will be the most disgusting thing you see all day. Maybe all week. That’s a guarantee, or double your money back. What’s the occasion? Today, all over the planet, is World No Tobacco Day, observed every year on the last day of May. Smoking gets a lot of publicity for lung cancer and heart disease, but the poster shows a few of its lesser-known but still common (and deadly) side effects. As the top caption says, people who start smoking in their teens (as more than 70 percent do) and continue for two decades or more run the risk of dying 20 to 25 years sooner than those who never light up. Your results may vary, but why risk it? You can click on the poster for an enlarged view.
