Not true! Casting high-level spells will age the caster. That is probably what is happening. Ressurrect, for example, I believe adds 5 years to the caster's age each time it is cast. Raise Dead may also increase the caster's age. Divine Intervention may as well.
Dsarvess: Well, as far as I'm aware, the only other source of aging in MM1 other than monster attack is going up levels.
It's not too much of a problem since the Rejuvenate spell can usually bring that age down fairly easily. If you're worried, head to an inn, sign in, then cast Rejuvenate a lot. If it keeps failing and increasing your age, you can just re-load the game and hope you have better luck. But I've usually been able to get a net age decrease from repeated casts.
There's another way to reverse aging in the game too, but it's hard to reach, to the point that I had finished the game and still hadn't been able to get there.
