[Belegorn]

Elendil was around 322 when he died. At that time the Faithful had longer lifespans than the Kings who's lifespans diminished to what Aragorn's was when he died, at around 210 years. This age was basically the lifespan of the average Numenorean who was not a member of the Kings house. Ar-Pharazon was feeling his time coming to an end at around 200 years. His father died before he was 200. These were members of the Kings Men. The Rebels. But remember, even though Elendil was old he was still like a young man. This condition still held for the purer families in Gondor during Faramir's time even though their lifespan was not much different from other Men. I personally think that the lifespan was the gift most effected by rebellion and the wish to escape mankind's fate than anything else.
