I'm not so sure about the blanket old people don't get jobs. If you look around supermarkets, DIY shops etc there are plenty of much older staff working for a pittance (in some cases) on zero hours or part time. I remember when you would not see an older person working in a supermarket etc. I think B&Q actively take on older staff who have experience of the work place because many have the right work ethic and the language and numeracy skills from previous employment.
