I am pretty sure Edi made a post somewhere that listed the magic path age modifiers, but I could not find it.

For the normal human, fire magic decreases the age at which you become old by two for every level. Example: XYZ human mage is a level 2 fire mage so he will become old at age 46. If the commander becomes old at a younger or older age, then fire magic will have a lesser or greater effect to remain in proportion.

Nature magic increases the age at which a commander will become old by 25 for each level for a human.

Once a unit becomes old, every level of death magic decreases their chance of getting an old age affliction by 30%. (All units get one year older every late winter. This is also when old age afflictions are handed out.)

I believe undead units and lifeless units had their old age level increased by death and earth magic respectively instead of nature.

Also note that being under a death scale increases an old unit's chance of getting an affliction in late winter while a growth scale decreases that chance.

Oh, and I don't believe that commanders with the heal ability are capable of healing old age afflictions. Just the chalice (an artifact) and the global Gift of Health are capable of healing those.
