If you sort group and age and use the stable option you can reshape your data using the reshape wide option
The stable option is critical.
Tjeck you data one million times when you have reshaped your data, so that pair 1 is a line. (there is a funktion in Stata that can do the checking for you, but cannot remember the name of it.)
Then do ttest varex1 == varex2
Hope it helps, and that i havent misunderstood your problem.
Mvh
