My mother 72 years old, bless her, has recently moved up from dial-up to broad band.
She has discovered Google and is actually using it a lot.
She'll see something on the news, google it and read more about it.
It has been a bit of a struggle to get her to understand not to open every email from unknown senders (" but they have send it to me, rude not to reply") and not to click on links promising discounts and free stuff.
So far so good.
Couple of years ago she was only using the computer to write a letter in word or send an email. Now she uses it as her window (no pun intended) to the world.
Don't underestimate how interested seniors are in the outside world.
