As summer approaches, get ready for Hollywood’s take on the apocalypse. You can check out the trailer for Will Smith’s upcoming movie After Earth. But my favorite part about the After Earth website is the survival tips it offers up from survivalist Les Stroud. He’s best known for his Survivorman series. Stroud is currently on location surviving somewhere alone for 10 days while filming. He always offers sound advice in case you’re ever in a tough spot. His best-known advice is “Keep calm. You sweat, you die.”
