Why do humans have disease, sickness and health problems? There are a few reasons:

You choose to experience disease and health problems as a life lesson. Many people do not know that they have chosen this as part of their life path. They have chosen it as a life lesson to learn from in order for them to attain soul growth. For those who have chosen it as a life lesson, they will have it most of their life. Even if the disease/health problem is removed, they still remember what they have gone through in their consciousness.
