When I was younger we had an old guy that lived in the house across the street from us. He had alzheimers but was the happiest old man. He would even joke about it and always say he loved it because he gets to meet new people everyday. He is never stressed because he doesn't bring any "baggage" from yesterday to today. And got to watch "new" movies all the time lol. His alzheimers wasnt that bad but he loved to joke about everything. I hope I can be that "happy old man" when I reach that age and not a bitter old grump.
