Bryan Johnson who wanted to live forever and called himself 'world's healthiest man' until an ugly diagnosis; now wants same for dogs

Bryan Johnson , the tech entrepreneur widely known for his anti-aging campaign centered around the motto “Don’t die”, is turning his focus toward dogs’ lifespan extension. Johnson’s interest in animal longevity emerged after he brought home a professionally trained Belgian Malinois named Katara to serve as a personal protection dog. During a recent longevity gathering in San Francisco, Katara remained by Johnson’s side while he encouraged tech workers participating in push-up fitness challenges used to gauge biological age.
