Welcome to the H2G2 Handedness Registry
Just to make it clear, I can't give you any good reason to pay any attention to this, but please do. The purpose of the H2G2 Handedness Register is to be a place where H2G2 Researchers can announce to H2G2 whether they are right-handed, left-handed, ambidexterous, or something else.
How to Register
To register, add a thread to this entry. In your post, say if you are right-handed, left-handed, ambidexterous, or unsure. Also, note if you are trying to change this (and if so, why). In a few days, I will begin posting the names of reserarchers and their stateds handedness.
Left-Dominant Ambidexterous Researchers
Right-Dominant Ambidexterous Researchers
Completely Ambidexterous Researchers
National Left-Handedness Day (in the UK, I think) is August 13.
