Have any other lefties found they’ve become pretty much ambidexterous for just about everything other than catching & writing & using a hammer?
No. I’m completely left-dominant; left-handed, footed, eyed. I’m a gibbon with my right hand.
I do very very few things naturally right-handed; about the only thing I can think of offhand is play pool / snooker. I do a few things right-handed like use scissors and shoot a bow, but these are learned behaviours due to unavailability of LH equipment rather than instinct. I use a mouse right-handed because when I first used one the cable / port position prohibited anything else (a happy accident because now I have my dominant hand on my dominiant input, the keyboard). I play Rock Band right-handed but air-guitar left-handed. (-:
I joked to my right handed brother this proves lefties are more likely to be multi talented and special
There’s probably a degree of truth in that. There is, I think, a correlation between left-handedness and Aspergers. For all its downsides, the geek gene brings a number of benefits.
eat with a knife and fork
I use a knife and fork the conventional way because the conventional way is crackers to start with. You eat with a fork in your right hand, but bring a knife into the equation and you swap hands? What’s up with that? Weirdos.
I found if I look on the side of the blade right handed people do, I can use right handed scissors in the left hand fairly easily.
The thing with scissors is the twisting action from your thumb pushes the blades together. Left-handed it’s reversed so it pulls them apart. If you’re conscious of this you can ‘pull’ counterintuitively to the left with your thumb and use scissors wrong-handed fairly effectively.
I used to play a bit of tennis and it really screwed my opponents up when I’d swap bat hand to hit a return coming off the other side.
Rounders at school. Yuks o plenty.
