I'm all over the place. I write left handed. Kick right footed. I can volley a ball left footed but can't strike a left footed dead ball for toffee.
Play guitar (if I could) would be left handed. Throw/bowl right handed over arm yet if it's a frizby type throw it would be left handed. Tie my shoelaces left handed, sew right handed. Hold a fork left handed, yet eat with my right fingers. Hold a cup and a pint pot left handed and yet squeeze a water bottle right handed.
Shoot right handed. Hold a racquet right handed. Wear my watch on my right hand where as most people are the opposite.
Throw one off right handed unless I'm telegramming the orgasm fairy on the old motty morse, then that would be left handed (comes in handy for multi tasking). Salute right handed (like I had a choice).
Scientifically speaking I think all my fine motor skills are left handed and the courser movements are right handed.
