I was more referencing the Night Lords and Alpha Legion, who generally don't spend time in Warp Corrupted realspace. Thats not to say that they don't recive mutations and so on, but generally speaking they are probably way less affected by the time altering effects of the Warp. I cite them because in spite of this they still have GC and HH vets within their ranks, alot like the others who spend most of their time in the Eye of Terror and Malestrom. And again, the fact that the Blood Angels do not visably age does pose the question if they actually degrade at all. And while we are on this subject, there are also the Iron Hands to consider, who eventually become little more than a brain in a metal body, I'm sure their lifespans would be considerably longer by both the virtue of being more or less a robot and the durability of that frame. So lifespan and even aging depends on the Chapter it seems just as much as factors of combat and time.
