Absolutely fascinating study of the amazing human mind. Written by as anthropotechnologist (yes, they have those in Germany), Spiegel digs deep into human evolution, the plasticity of the brain, and the beauty that can result in the union of (wo)man and an incredible machine. It's really deep into mindfulness and the joy that comes from the union of human mind with a talented partner (in this case a motorcycle but it applies to many -- horses, bicycles, musical instruments, etc.) Lots of great advice for motorcyclists for getting into flow while riding.
