For a short time when I was in my late-fifties I did some work for a charity which involved door-to-door selling. Most of my co-workers were half my age or younger, and it became obvious that I had some advantages over them because of my age. People of all ages are more open to a mature person than they might be to a youngster, and will listen to what you have to say. It might be unfair, but a young man arriving on the doorstep is likely to be thought less trustworthy than a mature person. Another benefit, which was pointed out to me by the boss, is that with my life experience I'm able to converse easily on a great many subjects. People in their twenties often find it more difficult to talk to someone older, because they don't have the same shared knowledge or experience. Can you think of other types of job where being a senior can be a big advantage?
