Hi, my grandparents are in the upper 80s and are still living independently. They could us some additional support around the house, cleaning, moving thing around, checking to make sure they have taken they meds, maybe some errands, and other assistance - and I'm sure they would be delighted to chat with you as well. The schedule could be very flexible. I am imaging maybe something like 3-5 hours per week to start, which could be one afternoon or perhaps a few check in through out the week, and could be based on your schedule.
