When biologist Hanna Bjørgaas spots a fairy cup lichen in Antarctica, she is surprised to recognize it from her own backyard in Oslo. When she returns home, she embarks on a journey into urban nature, visiting city parks, cemeteries, and concrete rooftops to investigate the species that live in urban spaces. Along the way, she meets corvids, songbirds, ants, pigeons, bats, sparrows, fungi, and linden trees—and the experts who study their surprising abilities to survive, and thrive, in the city.

DNA is "life's blueprint", encoding our genetic inheritance for health and life expectancy. Throughout life, DNA reproduces and replaces itself continually. In optimal conditions, DNA copies itself, making perfect reproductions. But as people age and their DNA is gradually damaged by the environment, diet, and physical and emotional stress, the DNA begins to reproduce poorly and ultimately stops reproducing completely. The result is disease and aging. In this groundbreaking book, Vincent Giampapa, MD, presents a radical new theory on how we age.
