I'm the Evil Righthanded Person. In fact, I'm so right-handed that when I shattered my right wrist (and required surgery, plates, screws, and
other amusing things to distract the airport security system) I had the dickens of a time getting around and doing things as a leftie.
However, the site ignores one very important clue: animals also exhibit "handedness" in about a 50-50 ratio. One of my cats is a leftie; the other
is right-handed (and dips water and food with his right paw.) Although mirrored universe creatures might not explode when they encounter each other,
the molecules of their bodies would be so incompatable they couldn't reproduce and they couldn't eat each other's foods.
This is why levulose (the "left-handed" sugar molecule) tastes great and provides exactly ZERO calories. We can't digest it.
Here's a nice (designed for kids but it's nice, anyway) page by the National Museum of American History's Science Center on lefthanded
molecules/mirror molecules.
