None of the older people at the Day Centre I visit to help with knitting have ever used a computer of any kind so, as others have said, referring to the fact that some, possibly many depending on age, older people do not have access to the internet is not unreasonable at all. Age does have something to do with using the internet because older older people have often never been shown and never felt the need to use it.
May of us in here are younger older people as opposed to older older people and the older older ones who do use the internet at home may well have had jobs where it was in use or just be interested and have felt the need. I don't think the people at the day centre I visit ever felt the need. Why would they?
My paternal gran never really learned how to use a telephone. She was born in 1892 and died in 1980.
