This is a great reminder and story indeed.
My mother in law lives with us and has had Alzheimer's for about 4 years. Needless to say depression sets in for her as she has lost her independence, unable to work or drive but we would rather her stay with us than go to a nursing home.
Getting back into pinball this past year has helped her out big time, its a way for my wife and I, and her to have real fun together and it has made a positive impact on her depression for sure. Im grateful to be able to have a machine at home now, more for her sake than mine.
