according to my mother's side of the family (who mostly took care of me when I was a small child, I did everything with my left hand, now I do m o s t things with my right hand so they think my nan (from my dad's side) forced me to write and do other things with my right hand. I still eat like a left-handed person though so idk what's going on

how many leftys here use a mouse left handed? I use my left hand and left click with my middle finger and right click with my index finger, as opposed to completely mirror to a righty. I think that's mainly because I didn't realise you could set the buttons until after I was use to using it that way.

I'm from Philippines and my parents say that being righty or lefty is based on the vaccine that is injected when you were born, which is either in your left or right arm. Then sees this video.
Me: My whole life is a lie

My mother and father are right handed, and so are my 8 siblings and grandparents but i'm the only one whose left handed. But my mom said that when i was young i used to write using both hands

Ever since physical therapy at 3 yo I've been a strong mixed handed person. Did everything 50/50 with both hands xD. Being 17 now, I'm ambidextrous like my dad

The lonely right-handers in this comment section of left-handers, why don't we try to be ambidextrous?
I'm starting to learn now. Come join me in this challenge!

reply

People say being left handed is rare but no one is talking about how being ambidextrous is even more rare. And a lot if not most people don't even know it exist
reply

Even though I'm left handed I still use my right hand for a lot of tasks so I could try to make my right hand dominant like my left hand.
reply

left handers make better leaders, and fewer leaders are needed than followers. Therefore, fewer left handers, more followers for us to make use of.
