In all of my lucid dreams I was myself and at my normal age! Non-lucids were mostly at my current age too, but there were some exceptions.
As for the memory test: I only remembered to do it in 4 dreams. Each time that I attempted to recall my address I was successful, for a total of 3 times. The other time I remembered the test, I started doing multiplication instead.

Only attempting the test 4 times was definitely the result of lack of willpower on my part . . . I kinda lost interest after my initial successes.
