Working among silver age?

[Daniel]

Hello, I am a very passionate volunteer who works in a retirement village. My job is to carry out computer lessons with a group residents. However I cannot progress my lesson due to the age limit that certainly exists.

I help them with facebook to keep them in touch with their relatives but most fail to remember the names therefore difficult to get in touch with their relatives.
Tried helping them with sending mails, checking stock prices and online card games and such. I am running out of ideas of what the residents may find interesting in internet.

The residents are between age 70-100, generation X that feels too old to adapt to generation N.
Please give me some ideas people, I can see so much potential in teaching how to use computer as it will certainly keep them entertained (They are normally very bored) and prevent demetia and such.
