Why are people left-handed or right-handed?

Tatia, First, I'm sorry you don't have answers yet. It's beyond frustrating for you I'm sure.

The brain is exquisitely complex. I'm not even sure a neurologist could sufficiently answer your question (Celeste's too).

Celeste, When I was young, I squinted a lot. I didn't know I had ptosis back then. I honestly think that my right eye is more dominantly droopy due to that early squinting. Though it could be genetic because my Dad squinted the exact same way.

Don't drive yourself crazy in trying to answer these questions!

Though, Geode, not having answers to your particular health issue would drive someone crazy. I really hope someone can figure it all out.
