Could dinosaurs be the reason humans can’t live for 200 years?

Not all animals experience ageing during their lives but for humans once they reach about age 30 their chance of dying doubles roughly every eight years. This high mortality reflects health problems, such as loss of muscle mass and general frailty, cognitive decline, loss of vision and hearing, etc.
