I'm particularly interested in knowing the proportion of people who write with their left hand in physics, mathematics and chemistry (students who completed at least 1 year at university/college or people who already finished their university studies; including therefore professors and people who switched area of work). I personally noticed lots of people writing with their left hand between my friends and professors hence my curiosity. Note: I personally write with my right hand even though I use my left hand/leg/eye for many things left handed people do. I'm only interested with which hand(s) you write, not whether your leg, eye and brain is "lefty"/"righty". I repeat, this poll is only for people who completed at least 1 year at university level in either of the three mentioned areas. Thanks! P.S.: If you voted, please specify your area of study in a post. I can (and do) use both hands to write but I'm more comfortable with my right hand.
