When I am 90years old, and have lots and lots of medical appointments. I hope someone is kind enough to find a 30 or 40 year old smart phone type device, I understand, for me to keep my appointments in.
AND I promise I won't ignore it and write all my appointments incorrectly on little scraps of paper stuffed in a book, or under the lamp, or next to the TV and then get all frustrated that the up coming appointments are not when I though they were.
