Old people tend to get tired and bored after retirement which can go into anything to get someone's attention, mental weakness as to something as basic as saying no to persistent people and believing they are taking on a new adventure.

Solicitors know this and take advantage of this. This is why political officials love to go by senior homes near election campaings, why your parents can go in a dealer with a beater compact and come out with the Fully loaded new version of the same model with ridiculous APR, why telemarketers used to get a game face as soon as an old grandma would be on the line ect.

On the other end, the Phone, the TV and buttons are what they used to live by, some kept up and are into social media, layered menus and verifying sources while others will still think if it came from the phone and is a polite person then it must be true.
