[40K] What lifespan can a human have in the 40k universe?

Do humans have a longer potential lifespan than? I assume for many human inhabitants of the Galaxy in the 41st millenium have a pretty short/normal life span by our standards - living in the bowels of a hive or on a death planet doesn't lend itself to a long and lasting life.

But what about humans that live on pleasure worlds - do they have a longer 'normal' lifespan, i.e. 200 years etc? 

Or can humans receive implants that extend their lives for hundreds of years (not including the Adeptus Astartes)? Inquisitor Veritus is said to have lived for over 1500 years, supported by power armour and arcane technologies. Is this something that senior members of the Imperium/rich planetary governors would also have access to?

Depends. Most people won't live very long given the poor treatment. Nobles and major members of the army can live centuries.

Tech priests and psykers have the longest lifespans potentially reaching the thousands of years. We know Malcador lived possibly over a thousand years during his service with the Emperor, we don't have much knowledge of how much longer he was around before his service.
