Chris Hemsworth says finding out about his higher genetic risk for Alzheimer’s has transformed how he views health, career, and family.

The 41-year-old actor learned the news while filming Disney+’s Limitless. Genetic testing showed he has two copies of the APOE4 gene, one from each parent, giving him up to a tenfold increased risk of Alzheimer’s.

He called the discovery both a warning and a chance to raise awareness. However, he rejected rumours that he was retiring or showing symptoms, saying such claims twisted his openness into false narratives.

The revelation prompted him to replace high-intensity workouts with a more balanced fitness approach, focusing on patience, listening to his body, and long-term health. He now includes mindfulness, mental rest, and brain-protective activities in his routine.

Hemsworth has also explored regenerative medicine, meeting Dr. Adeel Khan to learn about MUSE cells—special stem cells in bone marrow and connective tissue—which he hopes could support healthy aging.

Family life has become his top priority. Living in Byron Bay with wife Elsa Pataky and their three children, he now evaluates projects based on their impact on time at home.

While avoiding extreme biohacking, Hemsworth embraces realistic health strategies. He plans to return as Thor in Avengers: Doomsday (2026) and says future roles must have greater purpose. For him, longevity means living well, not just longer.
