Aging alters the body's ability to process energy primarily through a shift in body composition, according to medical experts featured on the Aging Untold program. As individuals grow older, they typically gain fat tissue while losing muscle mass. This physical change directly impacts how the body utilizes glucose for fuel.
Dr. Rhea Rogers, a board-certified physician, explained that the body functions like a power plant where every organ requires energy. When muscle mass decreases, the body's efficiency in using glucose drops. Rogers noted that if the energy supply for a high-demand organ is depleted, symptoms appear sooner. She cited the eyes and ears as examples of organs that show age-related changes early in older populations.
The program also addressed the emotional aspects of aging and mortality. Gerontologist “Sam” Cradduck emphasized that individuals facing the end of life should not feel pressured to maintain emotional strength for others. Cradduck stated, “You need to be getting the support that you need.” He observed that while family members are grieving their loss, they also have a role in supporting the person who is dying. Aging well coach Katherine Ambrose added that everyone handles these final moments differently, often dealing with grief, unfinished business, or complex relationships.
In Washington, D.C., Laura Lyster-Mensh serves as a death doula at Historic Congressional Cemetery. Her role at the national landmark involves promoting what she calls “death positivity.” She assists visitors in having healthy conversations about mortality to reduce fear and improve understanding.
A group of mall walkers in Oregon is using nostalgia to build community and physical activity. The group, known as the Food Court 5000, meets every Sunday morning for a three-and-a-half-mile power walk. Members dress in 1990s-inspired attire, including spandex, neon colors, and scrunchies. Founder Krista Catwood said the group has become “sort of B-celebrities” at the Lloyd Center mall. Catwood designed the activity to be silly, social, and shared to encourage consistent participation.
The program, produced by Gray Media Group, provides educational information and advises viewers to consult a licensed physician for personal medical advice. The segment covers metabolic health, end-of-life care, and community-based fitness initiatives.
