In this episode of After Hours Clinic, Andrew Lane and Dr. David Janarious examine a timely question at the intersection of longevity, fitness, and alcohol use. Using a recent population study from Norway as a springboard, they analyze whether cardiovascular fitness can lessen the mortality risks associated with alcohol consumption.

The conversation addresses how alcohol is often underreported in clinical settings, why fitness may be one of the most powerful lifestyle factors for long-term health, and how changes in fitness over time influence risk more than absolute performance levels. They unpack hazard ratios, observational study limits, and why declines in fitness appear especially harmful. Along the way, they reflect on personal habits, cultural norms around drinking, and the idea that it’s never too late to improve fitness and reclaim meaningful health benefits.
