I have a question, well.....I could answer it myself so it's more of a statement =)
How old is Alric? In myth 1, we know about Alric living in covenent during his "youth" before the dark sacked it (flight from covenent journal). which places him anywhere between 10 and 20 years old. Then we know the war continues from 17 to 30 years after that, placing him between 40 and 50 years old.
Enter myth 2.....60 years later. Alric is still around and in good shape (just look how VICIOUS! he fights!!!!). And he is over 100 years old.
Is he immortal like the journeymen/heron guards? Does the use of magic extend his lifespan? Did Bungie simply overlook this matter?
