I have a mother who has Parkinson’s and was interested to read about your 76 year old “retired teacher.” A title my mother holds too - she is 80 years old. I like the spirit of your idea, but practically speaking, my mom, who was fairly technologically literate can not use technology any longer. Parkinson’s has an “executive functioning” dementia component to the disease. Simple tasks like remember how to use the phone or remembering peoples names is difficult for my mother. My suggestion is that you look at the demographic that would interact with “Vikarious” and make sure that it’s demographic appropriate. If you’d like to talk further let me know and I’d be happy to clarify.
