Ok, death magic and afflictions, what's the deal?

That is a bit odd then Ano. I've often wondered if how far past the "Start of Old Age" mark a unit is plays a part in it somewhere along the lines. (either in years or as a percentage of their lifespan). Have never seen anything mentioned anywhere on it, but I'm sure I've noticed that units which have just crept over the old age mark seem far less likely to pick up old age afflictions than units that are well past it.
