You must see The Bootleg Beatles. You will be amazed. They sound better than the real Beatles probably did. There is a snag though. "Paul" plays his Hofner Violin Bass right-handed. It does not spoil the show, but you notice it, especially if you are a raving leftie like me - left-handed, that is.
There is an interesting piece in The Times about being left handed, and the role it plays in learning and development.
How does it affect me? The most noticeable thing is walking down the street; you bump into people because they always walk to their left to avoid you. A leftie would naturally walk to the right. I have long learned to work at this, but occasionally I forget, and a near collision occurs. Doors are also designed for right-handers. Skating rinks and race tracks are a problem, for the leftie naturally wants to go anti-clockwise.
Otherwise, I have no idea how different I am. I am generally aware that I tend to think impressionistic, rather than linear thoughts. I am crap at everyday narrative. If someone says, "What's going on?" my answer would entail a summation of the mood, rather than a news report. I am also, tragically left handed. If I lost my right arm I would not miss it.
Mrs Weasel is also left-handed. We are both a bit strange.
