Left-Handedness

According to the BBC:

Left-handed people can think quicker when carrying out tasks such as
playing computer games or playing sport, say Australian researchers.

more specifically:

Extreme left-handed individuals were 43 milliseconds faster at
spotting matching letters across the right and left visual fields
than right-handed people.

It only works if you’re caffeinated, though. I should say, it only
works for me that way.
