=== Lifespan ===
Each leader has an age in years and has a base guaranteed {{iconify|Leader Lifespan||||lifespan}} of 80 years, which can be improved by certain species traits, leader traits, and technologies.

After passing their guaranteed lifespan, leaders have a chance of dying every month. The probability is {{red|0.2%}} per year that has passed since their guaranteed lifespan. After 20 years past their guaranteed lifespan this increases to {{red|2%}} per month. The mean lifespan with no modifiers is 88 years, 6 months.

Hovering over a leader's age will show the leader's guaranteed lifespan and current chance to die each month. Rulers of {{icon|Hive Mind}} {{icon|Machine Intelligence}} Gestalt empires are immortal.

The following modifiers affect Leader Lifespan:

==== Death by accident ====
While {{iconify|Mechanical}} and {{iconify|Machine}} leaders are immortal, they can still die by accident, regardless of their age. Every 10 years, there is the following chance of a leader suffering a fatal accident:

* 88%: nothing happens
* 2%: Survey Ship scientist dies
* 2%: Engineering Research Leader dies
* 2%: Society Research Leader dies
* 2%: Physics Research Leader dies
* 2%: Admiral commanding a fleet dies
* 2%: Governor governing a sector dies

Note that this is rolled per empire, not per leader. For a role with exactly one leader, this represents a mean active lifespan of 500 years. An exploit to negate the chance for accidental death entirely exists: remove each leader before the decade begins then returning the leaders after a month passes.

{{expansion|snd}}
{{iconify|Machine Intelligence}} empires can adopt the [[File:Tradition_synchronicity_self_preservation.png|18px]] Self-Preservation Protocols Tradition to reduce the weight of accidents by half, reducing the chance for an accident to occur for each role to 1.06% (6.38% total), for a mean active lifespan of 940 years.
