• About 90% of people are right handed and you might either generally forget that left-handers exist, or think that their prominence in society is overstated
• The appropriate response to discovering someone is left handed is to say "oh" and move on with your day
• Being left-handed can be mildly inconvenient as most things are designed with right-handers in mind -- but not enough to really cause a stir
• People tend not to believe people when they say they are "truly ambidextrous"
• A lot of societies, especially back in the day, would force left-handed people to use their right hand for everything
• Once it became more acceptable to be left-handed, reports of left-handedness rose from a mere 2% to over 11%, particularly among the younger demographics (18-39).
• In some cultures, the left hand is considered "unclean", even though in modern society that's kind of a dumb idea
• And much like being gay, left-handedness is something you're born with, can't actually control, and doesn't actually say anything about who you are as a person. It's just different, and that's okay.

Thanks for coming to my Ted Talk.
