With all the problems in the world, there should be at least a few where you can get paid to find solutions. Lo and behold, there are some problems that you can totally get armloads of money for, sometimes for simply sitting in a chair and thinking about the answer. Problems like…

Find out how our numbers stack up against everything from bugs to bacteria, and get ready for some mind-blowing numbers!
