"King Charles III: Health, Service, and Challenges Ahead"

As King Charles III takes the British throne at 74, experts speculate on his health and longevity. He comes from a family of "long livers" and has been a great steward of his health. He has suffered injuries from playing polo and hunting, and his trademark walk with his fingers interlocked behind his back may be a way to relieve back pain. His posture has also been a topic of discussion, with some speculating it may be related to osteoporosis. His hands have been described as having "sausage fingers," but experts say it may be his baseline and not suggestive of any underlying disease. Understanding the biology of people who live to exceptional ages could help discover medicines that can help us all live longer and healthier.
