Why do you need to think for 30 seconds about which lottery numbers to pick. You're not winning, grandma. I've been carrying 3 2L bottles without a basket while standing in this line for the past 5 minutes and I'm ready to kill.
I also have an odd one! My left hand does all the work and I ONLY use my right index finger. Maybe sometimes my middle one. I regularly score >140wpm so I don't see a need to change it.
