Back in the early 1980s, pitcher Bill Lee, a noted oddball, was interviewed about being lefthanded. He replied:
“Science tells us that righthanders are dominated by the left half of their brains and lefthanded people are dominated by the right half. So there’s proof right there that lefthanders are the only people in their right minds.”
My grandmother was born in 1900 and grew up lefthanded. Later, it was discovered that she had been born with a broken right collarbone explaining why it hurt to do things with her right arm so she naturally learned to write, throw, etc. with her left arm because it didn’t hurt.
I have seen people born with no arms learn to do incredible things with their bare feet so our limbs can adapt to make up for the lack of other functions.
My youngest brother seemed to be leaning to be left-handed as an infant, then broke his left collar bone as a toddler (from a fall, I SWEAR). I think he had to wear a sling for a couple months, but truly don’t remember the details. He ended up being right-handed.
