That sounds like a simple hypothesis with a simple test. And then there are several simple hypotheses. For each: Compute (A-B). The one-sample t-test, against 0, says whether A is generally greater than B. Or, two one-sample t-tests can be used if you want to see if there is a strong effect for 'Older' (however you find them) or an opposite effect for 'Younger'. To test Older versus Younger usages as a linear trend, correlate (A-B) with age.
