Perseverance of man with hemophilia inspires others

Despite standing 1.7 meters tall, Xiao Tan, from Changsha in Hunan province, tries to maintain a weight of around 40 kilograms.

This is not because he has an eating disorder, but because he has a rare condition known as hemophilia, which means his blood doesn't possess the needed proteins for clotting.

While a small cut is not an issue for most people, for those with hemophilia it can be potentially life-threatening.
