Quick question: getting diseased

[Tuidjy]

Does having regeneration (intrinsic or from an item) reduce the chance of getting
a disease (from old age, C'tis domain, Burden on Time, sites, etc...)

By the way, there was a rumour in Dominions II that some battlefield spells can
cure afflictions. Has anyone seen that happen?

Yeah, before you ask, I am playing an old age nation, and despite a Life domain,
a decent nature blessing and a Shroud of the Saint factory, I feel as if I'm
running a hospital, not an Empire.
