Moving right along the biography explains, "His post office was the first to deliver mail straight to people's houses." Ben Franklin's accomplishment of creating a post office to deliver mail to people's houses helps people get their mail. Some people may not be able to drive to get their mail. What he invented next will have you jumping for joy. I am grateful that Ben Franklin showed people how to use an iron rod so lightning would not burn up houses or ships. He loved helping people, and Ben Franklin's wonderful invention of the stove helped people heat their homes more quickly. Another invention that I liked was his invention of bifocals; they help people see near and far without having to switch out glasses. Finally, I think that Ben Franklin was a curious, intelligent person that invented an odometer that helps people measure the distance they traveled.
