"Aging" can cover lingering work-related injuries, lingering effects from treated mishap injuries (it was always odd to me you could buy those off completely), minor radiation damage, losing the strength or wind you had in your twenties. They don't have to be literal geriatric decrepitude.
There's also a meta-game aspect. Parallel to how "death" in Classic char-gen really meant "you pushed your luck too far, start over, and consider a lower term count the next time you get good stat rolls," "aging" starting at 34 really means "you can try for lower or higher, but the game softly encourages characters centered around 4-5 terms, so pushing past that has a trade-off."
Well, there it is. This is the worst possible reason to make a change to the rules. It's a house rule. If you want to house rule it, house rule it and carry on. If you want to discuss your house rules, that's fine too. But this kind of thing should be kept far away from the rulebook.

Even so, Traveller should make the changes to account for that as 34 has always been too low a bar for my taste.
