They don't put the age condition on the service schedule for no reason - the materials the belts are made of (particularly rubber-based ones) perish and weaken over time. This occurs due to exposure to temperature extremes, to motor oil (and other substances found in the engine bay). Same goes for the metal ancillaries to the belt - the tensioner etc. Sometimes this damage will be visible, sometimes it won't.
