In the '70s or early '80s, NASA discussed handedness in terms of alien life -- if there were viruses and other forms of life on Mars, they might be incompatible with our biology by reason of being left-handed. One NASA scientist quickly took out a patent for left-handed sugar. It would have to be created in a lab, but its inability to interact with the human digestive system means it would sweeten foods without producing weight gains or rotting teeth.
