I'm 64 and I couldn't live without internet now either LouP, I use it to do so much (but it is a time waster too, for me at any rate!) But our elderly parents , DHs are 89 and 90, and my mum is 89, can't used it at all, so we manage my mum's energy accounts and her car insurance for her, ensuring she gets the best rates. We also find out things she needs to know and give her the information. However, DHs parents are different, they don't want to disclose any information to DH about financial affairs and reject any offer of help from him, so obviously we respect that, but is still difficult when they tell us that they prefer to keep with the same energy provider because they've been with them for years and `always been very good` as we know they're not getting the best rates available to them. Still DH has offered, that's all he can do.
I too feel a little offended when people say older people can't/don't use the internet, I think the age should be qualified, so many 85+ people don't use the internet, but even them it's a generalisation because there are 90+ people who use the internet.
