Left hand vs. right hand when keyboarding
Despite never using the left thumb to type, my left hand has to do the heavy lifting when it comes to the number of letters it's responsible for.
Left hand is responsible for 15 letters:

Right hand takes care of 11 letters:

Maybe that's why I use my right thumb for the space bar, my left hand is too busy typing the majority of the letters.
