Healthy aging starts with physical resilience, the body’s ability to withstand and recover from stress. Maile Young Karris, M.D., defines the concept and sets the stage for practical strategies that match real-world needs. Ryan J. Moran, M.D., M.P.H., recommends simple routines such as wall push ups, posture alignment, and chin tucks, and he links posture and vision to fall prevention; social connection helps people stick with movement. Theodore Chan, M.D., F.A.C.E.P., F.A.A.E.M., explains that age alone is a poor predictor of outcomes in acute care and that functional resilience strongly influences decisions. Gail Levine emphasizes accountability, community, and balanced nutrition. Moran highlights protein needs of about 1 to 1.2 grams per kilogram plus calcium with possible vitamin D, and he favors plant focused eating with limited processed foods.
