Makes sense but would you buy anything from a person you find distasteful - No. So why add all the psychobabble - you buy from a salesperson that you like. You turn off the TV when someone you dislike comes on. I imagine that shopping channels audition lots of people for a host position - trying to find one that is universally pleasant and able to sell. I don't think it is particularly aimed at the elderly.
And to assume, in this day and age, that elderly people are more susceptible to selling tricks is outdated. I was shocked when I discovered I am just 6 months away from being considered (gasp) elderly!!! I just started working with a 22 year old and I have never listened to anyone so naïve - it's amazing some of the things that come out of her mouth.
