      That’s a hard one to answer. Sometimes there are problems with the synthesis of their genes early on, or they inherit genes that have some problem in this sense. There can also be problems due to exposure of toxins or disease, or from a lack of essential nutrients in the womb. Other diseases, we do not know enough about to say why they happened.

      I don’t know. Probably something to ask a biologist?
