There is no exercise better for the heart than reaching down and lifting people up
Helpfulness refers to the state of being helpful. Every single person on earth needs to try and improve their helpfulness, this would make society a much better place. If you have a can that you need to open then the helpfulness of a can opener may be invaluable, especially if this is the only thing you have to open the can with. Sometimes your helpfulness may be a simple smile or holding the door for someone when you are entering a business.
