How many things can you think of that have come out in your life time? I can think of several and it blows my mind that these things came out AFTER I was born. Some things that were around long before I was born have become better since after I was born however like the waist purse water bottle system. Water bottles used to have to be carried around manually but these days you can carry them around your waist, a simple but very necessary innovation that is used a lot. A lot of things are simply innovations of things that were around but not as good as they were. Think of the television remote control for example..
