Don’t Stand By Me – Surviving a lightning strike. By Joshua Foer: “Unlike garden-variety electrical shock, which finds the quickest route directly through the body, lightning can flash over the outside of a victim, sometimes blowing off clothes without leaving so much as a mark on the skin. The high-voltage electricity that zips through the body does its damage in just a few milliseconds. In many cases, there are no visible burns, though temporary fernlike bruises called Lichtenberg figures sometimes appear. Medical tests like MRIs, CT scans, and X-rays usually come back normal. But those are anatomical tests of how the body looks, not functional tests of how it works, and they can be deceiving. Zap a computer with an electrical surge and its hardware will appear unchanged, but that doesn’t mean it’ll still be able to run Leisure Suit Larry. The same is true of humans.”
