Great data, thanks for sharing.

I think one of the "problems" is that innovation is actually picking up speed dramatically. So even if the politicians aren't older, they are more likely to be removed from relevant business and innovation cycles and also more beholden to entrenched businesses.

Average term length has continued to rise as well. (see http://www.fas.org/sgp/crs/misc/R41545.pdf page 6)

In 1949, a Senator on average served just 1 term (6 years), and a Representative served 3 terms (6 years).

Now, in 2013, a Senator serves nearly two terms (12 years), and a Representative serves nearly 5 terms (10 years).
