The 100-Year-Old Harvard Doctor’s Secrets to Graceful Aging: Lessons from Dr. John Scharffenberg

6. Avoid tobacco and alcohol

Dr. Scharffenberg advises complete avoidance of tobacco and alcohol to slow the aging process. Both substances accelerate cellular damage, increase inflammation, and raise the risk of chronic diseases such as cancer, cardiovascular disease, and cognitive decline.

7. Community and purpose

Strong social connections and a clear sense of purpose are powerful contributors to graceful aging. Engaging with faith-based groups, volunteering, or participating in community activities helps lower stress and enhances motivation.
