Phil chats with Professor Grant Tomkinson from the University of South Australia about a study linking finger length to fitness.

The research shows people with shorter ring fingers compared to their index fingers may perform better in endurance sports like marathons.

This finger ratio, called 2D:4D, is thought to reflect prenatal testosterone exposure and may influence lifelong athletic ability.

The study, published in the American Journal of Human Biology, analyzed data from over 5,000 people across 12 countries and found those with lower 2D:4D ratios had better endurance and exercise tolerance.
