That was an awesome share and I really appreciate it. One of the things about left-handed people although we are only 10% of the population we have been over 40% of the population of well-known scientists and mathematicians. Over 20% all all hardened criminals. Over 20% of politicians. And 100% of the time have never been in a fair polo match...Here is a hero for all left handers - Elizabeth Cotten - born 1893, too poor to buy a left handed guitar, she took a standard guitar and turned upside down and developed her own unique style, picking the melody with her thumb on the lower register. This is her signature song, which is sort of a folk song standard, and if you listen to a right handed player play, the music isn't the same.
The one piece of equipment that I know of that was designed (as an unintended consequence) to favor left handers is the classic QWERTY keyboard. The inventor of it (and an early version of a typewriter) put all the common letters on the left side of the keyboard to slow down typists so they would not make as many mistakes.
(old guy question - who has ever used a manual typewriter for serious business?)
It's a heavy burden to carry knowing that you are smarter than 90% of the population.
What's really odd is that there is no satisfactory explanation for "handedness" in humans.
