This Is Interesting... I Use Two Fingers on left Hand...And Three Fingers on Right Hand... As my Little Fingers on Both Hands are Bent...They are Pretty Useless for typing...And so Stick up at an Arkward Angle...Which Means I ac Not Type Contiunously for a Lonf Period of Time... So I Type With 5 Fingers Altogether...
I never realized it but I don't use my left thumb either! I'm lucky I took typing in school, my hubby uses his two index fingers! But hey, he never misspells anything because he puts so much effort into finding the right letter key.
I use both hands, all fingers and thumbs around 80 words a minute kinda slow and if I get really excited I have an 11th digit do the space bar instead.
