So what am I if I can’t throw or catch with either hand, but close both eyes when the ball comes towards me?
Uncoordinated? 
There’s actually a term for that: ambisinister, sinister being the Latin word for left-handed!
When we were kids, my best friend played tennis with two forehands.
At school, when his hand got tired writing, he’d simply switch and write with the other hand.
Ambidextrous!
The only problem was that his forehands were both abysmal and his penmanship illegible.
Neither-dextrous.
I’m strongly left-handed (right-hand mostly useless except for typing and mousing) and DH is mostly left-handed. My mom started out left-handed but was forcibly switched. 
My MIL is mostly left-handed like DH.
DH and MIL are left-handed except for batting in baseball – which is dumb because being a lefty is an advantage.
Kids are both right-handed, despite some encouraging to try the left hand. Such a disappointment… :)>-
This is the handedness questionnaire I used for my dissertation. http://faculty.washington.edu/chudler/rltab75.html
I am very left-handed. The only thing I do right-handed is serve a volleyball and use a computer mouse.
How many of you changed your self-report of handedness after taking the survey?
I am very left handed. My mother was very left handed but had a flukey ability to write SIMULTANEOUSLY forward with her right hand and mirror write (backward) with her left. She’d start in the middle of the page and write the same thing forwards and backwards with both hands. It was eerie.
Of my 2 sons, one is left-handed (DH is right-handed) but lefty son plays baseball right handed (throws and bats) He is not a switch hitter.
Thanks for the questionnaire @jym626! I’m a -24 female.
Did you ask about handedness for computer mice? I learned to mouse in a computer lab where all the mice were on the right side. Also, the useful keyboard letters are mostly on the left hand.
@Ynotgo Computer mice didn’t exist when I did my dissertation!! We were barely out of te punchcard/cardreader computer days!!! And most people learn to use a mouse right handed because thats where its placed by the computer. The volleyball question is also not on the questionnaire. Its just the only thing I do righty.
I can’t even picture serving a volleyball righty, and I have a pretty mean lefty serve.
I steady the ball with my dominant (left) hand and hit it with my right.
Yes, that was interesting. Thanks, @jym626!
I came in +3, so solidly mix-handed. I just remembered when I took the Myers-Briggs test years ago I straddled two different categories. I wonder if there’s a correlation?
Its not uncommon to be close to center on any 2 categories on the MBTI,and its not likely to be highly correlted with handedness, I don’t believe. I actually found my MBTI printout from grad school (printed on a dot matrix printer) and I was close to the middle on one of the 4 score ranges (judging/perceptive) . But we are getting off topic so lets not go there.
I was -24
Leftys unite!!!
Ok wait-- the old trackball computer mouse was probably around when I did my dissertation, but only at the very end of my graduate career did we have dumb terminals available to us (the computer and printer was up at the med school library.
Ok… my bones are creaking…
Solid -24 here as well. Left-handed mother, right handed father. Have two strongly right handed kids and one I used to call null-idextrous. Equally bad with both hands. Eventually settled on being a righty.
Far more lefties reporting here than odds would predict. I suspect that lefties are more likely to click on a thread about handed-ness than righties because it’s more of an issue with us than with the 90%.
The only things I do right handed are using the computer mouse and using the number pad on the keyboard - both of which are just easier to do right-handed because of location.
Yes, the keyboard stuff is all I really do too just because of location. I did play guitar right handed but I had a right handed guitar teacher and you really need to be able to use both hands anyway. When I was a kid, I also kicked left footed in kickball.
thanks @jym626 ! I’m a +5. Certain things I have to do lefty- open jars, loosen nuts/bolts. Other things I’m ambi. Hand S are right handed- the left arm is there strictly for symmetry and balance. Glad I didn’t know I was supposed to have ‘issues’ with learning…
Lefty also, although I can do the mirror writing (as could my great aunt), and I do a lot of things with either hand like play violin or throw clay on a pottery wheel.
