In our culture steaks/wine/cheese are considered better when they are "aged."
Not so much so with people who are often thought of as "useless eaters."
In some other societies, old folks are respected, even revered for their function of maintaining the essential lore and their ability to disseminate it.
The World Wide Web is "age-neutral" and although one's sensory faculties are gradually impaired as time goes by, in general sanity is retained.
Does just age preclude participation? Some of us believe that we can keep on keeping on with our Web activities.
