several brain-scan studies have verified a fundamental difference between left-handed and right-handed brains. A right-handed person's brain is typically highly specialised, with a specific portion of the brain dedicated to each task. this same specialization is much less prevalent in left-handed brains. so, no.
also people who are left-handed are technically said to be sinistral, and left-handedness is sometimes referred to as sinistrality. both words derive from sinister, the latin word for left.
not only daft but dangerous as well
