Via Sullivan, I suddenly feel very old:

We extracted about 75 percent of the responses on age (representing about 700 responses, taking equally from the earliest and most recent postings, which show very similar age distributions). Per John Makinson's quip at an LBF panel, over half of reporting Kindle owners are 50 or older, and 70 percent are 40 or older.

So many users said they like Kindle because they suffer from some form of arthritis that multiple posters indicate that they do or do not have arthritis as a matter of course. A variety of other impairments, from weakening eyes and carpal-tunnel-like syndromes to more exotic disabilities dominate the purchase rationales of these posters.

Wait! I'm not 40 yet! And I see just fine, with a little help.

This, on the day that I took a final exam in a class (Introduction to Microeconomics) in which every other student was younger than half my age. Yes, there were about 50 of us in there, and the day the Berlin Wall fell down I was older than they are now.

Sigh.
