Not to pick nits, but the Boomer span is generally given as 1946-1964. This is been trumpeted as the year the first boomers turn 60.

>So not that much changes - we still have a group that's younger than some of you thought (at least for this sample). Many of you guessed at the averages when you emailed me your age. The most common guess as to our average age was 58. We're way below that, at least according to this sample...
