Hmmm...I use my left hand quite often too.
Scratch head
Scratch right arm
Hold handphone while not driving
On the radio
Change gear while driving
Clutch in while riding my scrambers
Wear my watch
Put on my ring on my right hand
Cock my MP 5 and changing magazine
Take things out from my left pants pocket
etc......
Looks like my left hand is doing lots of stuff to compliments my
right hand.
