How long is the average life span of a person with haemophilia?

Haemophilia:

1. Hemophilia is a rare disorder in which the blood does not clot normally due to a lack of blood-clotting proteins (clotting factors).
2. Hemophilia is a recessive sex disease.
3. This causes people to bleed for longer after an injury, bruising to be easier, and an increased risk of bleeding inside joints or the brain.
4. A hemophilic patient's life expectancy was previously just 11 years without therapy.
5. With treatment, the average lifespan has now risen and is just 10 years shorter than that of the average individual.
