I am old enough to have to start thinking about the mortality of my own parents. The biggest concern right now is my father. He is struggling with Parkinson's disease, which went untreated for a long time in spite of his suspicions, because he refused to see a doctor. Please don't make his mistake. He is getting full-time care in a home, so the situation is not as stressful as it used to be, thankfully. He has ups and downs, but just seeing his old neighbour who is roughly the same age and struggles with the same condition, you can tell the difference. He went to the doctor.
