The Graying of CW

I made a QRP entry for ARRL SS CW. It was my first significant effort since 2001 and a near match for that year's result. I claimed 198 QSOs and scored around 26k. Spent most of my time on 40, followed by 20 and 15.

As mentioned here, I got curious about the check pattern and did a little calculating. The only way I can read this result is that CW contest aficionados are aging. I don't suppose this comes as a surprise.

Number of Years Since First Licensed (mean±SD)
40.4 ± 12.6 years

I received just one check from the 21st century. That's about one-half of one percent. Kinda gloomy.

I had a lot of fun, anyway, except when cursing my inadequate antenna. How'd you do?

EDIT: A few hours after I posted this, I realized my sample may be biased. My contest mode was search-and-pounce for all contacts (I called CQ a few times but attracted no attention). Newer ops may be less likely to CQ in a big contest, so I wouldn't have worked them. I still think there's a pattern here, though.
