She had us all in stitches when she told us about trying to brush her teeth with her left hand. I tried it myself and it's a totally weird experience ! Your hand has no control whatsoever over the toothbrush !
This set me think about ambidexterity. It must be very handy to be able to use both hands for tasks. It seems that most people are right-handed. Some 10% of the world population is left-handed. Only 1% is ambidextrous.
Ambidexterity may also be associated with an unusually symmetric brain structure. Most people have a dominant side of the brain that is opposite to their hand preference; right-handed individuals have a dominant hemisphere in the left part of their brain and left-handed people have a dominant right hemisphere.
If you want to try to become ambidextrous, try the following;
Practice is the key. During the day, use your left hand more (if you're right-handed) by consciously switching when you're about ready to do something -- pouring a glass of milk, bouncing a ball, cutting and buttering bread, stirring your coffee, swirling water in a glass, twisting off bottle caps, etc.
