If you never stop, you'll never have to stop.

If you do stop, once your over 45, start back by doing chinups only for a while. Do curls, using a dumbell and hammer curls, get your biceps engaged often, make sure your core is strong from planks and various types of situps, use kettlebells to get your lats and grip strength back, then pullups won't be nearly as daunting.
