Hi Robert,

     Do I understand you are suggesting heating an LPRO, not cooling
it?  That seems to go against what I understood, that greater cooling
leads to increased life.

     As an aside, a newbie question if I may: being so used to Caesium
standards being THE reference, I was surprised to hear that the CSAC
has an aging mechanism - can you say a few words to explain that
please?

          Peter
