We are all different, and a disease that I might have, if I had Alzheimer's disease or Parkinson's disease, it probably would affect me differently than if one of you had that disease, and if we both had Parkinson's disease, and we took the same medication, but we had different genetic makeup, we probably would have a different result, and it could well be that a drug that worked wonderfully
