Save the javascript url below as a bookmarklet and run it on a bugzilla query list of bugs to get basic age stats for that buglist. The answers will be shown in an alert as well as appended to the bottom of the document. It will look something like:

  total: 7
  median age: 13 days
  oldest: 235 days
  median last touched: 3 days
  least active untouched for 189 days

Caveats:
1. This works at bugzilla.mozilla.org. I have not tried other bugzillas
