Are You a Leftie or Righty?
The left-handed brand has had quite the uphill battle. Catholics famously shunned left handedness, although there was never an actual Church teaching on the matter. In some cultures, the left hand is considered unclean, and it’s considered rude to offer your left hand in greeting.
Rather than chalking it up to sorcery, scientists have been studying why some of us are not right handed, and they’ve found that hand preference actually begins in the womb, sometimes as early as 13 weeks. If you’ve ever seen an ultrasound of a little thumb-sucker, you may have had a similar insight.
