Here's a good reason to make sure that your folks/grandparents are
online - it decrease the likelihood they'll suffer from depression!
If they aren't set up, they may need help - be sure to set their
screen resolution to something suitable for older eyes, and set their
browser for a larger font if they have more severe vision problems.
My mom is set up with the old standard - 600x800, and that works fine
for her (she has vision issues).
