User blog comment:Argorrath/Black Ops III - Menendez will not be returning/@comment-26299686-20150625175836/@comment-1187559-20150625191643

Even in the year 2060, I don't think we'd have the tech to replace most of the major organs that start failing around age 100. And given the brain is one of those, we certainly wouldn't have the tech to replace that, or give it longevity. So I think it's not greatly possible for Menendez to still be alive should he have finished BO2 in a living status. So come BOIII, he'd either have died of natural causes, been killed by Mason, or have committed suicide.
