the general elderly person is never the best with technology anyway
I used to work in domestic computer repair and support before my current job. There were no end of people who came in to where I worked who were in the ages of 60 to 90 and had no issues using a computer, a few even knew how to build them. They didn't know how to get them working again when they broke which was where I came in, did whatever was needed to get it going again and gave it them back. Fully competent in computer usage, so it probably stands to reason they can work the Sky box and the TV too.
You might want to reconsider your (probably inadvertent) stereotype of people past a certain age who can't work stuff...
I will do, it's just that this is what I'm used to. My grandma's friends often come to me if they need help with anything as they know I'm alright at it. It's usually something simple like "how do I upload this video onto Facebook" or "how do I get this on catchup" or something. I also help out at a club at the local library for the elderly to learn how to use computers. I'm not saying that's everybody because my grandad impressed me the other day by installing Linux onto his computer from a USB stick, so there are the ones that manage to fend for themselves, and you're absolutely right.
