I worked for an 82-year-old neighbor, Sue for a year because of her vision loss and inability to do many tasks for herself. I did things like taking her garbage out and back, taking her pets to the vet, light yard work, getting groceries, and many other odd jobs along with companionship.
My experience is from my personal day to day life running my own errands and daily "adulting", as well as having worked as a personal assistant for corporate individuals that simply needed a few extra hands to keep everything organized and running smoothly!
