It is stressed that the first and most obvious thing to look at is the universe itself, or at least its global dynamical aspects as imprinted on the galaxies etc. The 'change' that one is seeking in order to obtain an age is, of course, the change in the separation between the constituents of the universe. The introduction of physical models for interpreting the observations prevents rapid progress. The problem at present lies not with a lack of ideas or insights but with the application and input of intricate and tedious physical theories and data into gradually improving computer programs. With respect to the globular clusters, it may well be time for a revolution in stellar evolution calculations in that the goal should be 'realistic' two-dimensional calculations that include rotation from the pre-main sequence onwards.
