#5 should have been #7. I am neither sure nor guessing. I read a book which gives the reasons why more people use right hand and that make right hand stronger. Another reason is women tend to use left hand to hold babies becasue the heart beats can calm down the babies and make them falling asleep more easily. So women use right hand more during the years that they have young children.
