http://people.debian.org/~spaillard/developers-age-histogramm/ actually also
contains historical data.
Fortunately, it also shows the average age increases slower than time: over
2012 (12 months so), average age increased by 2.7 months only.
Consider the figures below with caution, as it's computed from rounded to year
data, hence the big jump at year transition.
2010-04-11 mean = 33.1036
2011-03-19 mean = 34.0884
2011-05-13 mean = 34.0711
2011-06-01 mean = 34.107
2011-07-01 mean = 34.107
2011-08-01 mean = 34.0982
2011-09-01 mean = 34.0963
2011-10-01 mean = 34.0879
2011-11-01 mean = 34.1322
2011-12-01 mean = 34.112
2012-01-01 mean = 35.1168
2012-02-01 mean = 35.0846
2012-03-01 mean = 35.1131
2012-04-01 mean = 35.0561
2012-05-01 mean = 35.0864
2012-06-01 mean = 35.0668
2012-07-01 mean = 35.0569
2012-08-01 mean = 35.052
2012-09-01 mean = 34.9782
2012-10-01 mean = 34.969
2012-11-01 mean = 34.9706
2012-12-01 mean = 34.8928
2013-01-01 mean = 35.8746
2013-02-01 mean = 35.8918
