These, and so many other questions stare us right in the face every single day. But instead of searching for answers, most of us just choose to look away. And thus, so much of life remains a mystery. It should not be this way. There are people out there, entire communities in fact, that have already done the leg-work of experimenting with different solutions. And all you have to do is to take advantage of their findings. This book brings you face-to-face with such difficult questions, and presents possible answers that are inspired by a wide array of subject areas and communities.
