In the new TW 2013 system then have some called survival points based on age, etc. You get an allotment of them and can use them to modify an attack roll, less the severity of a hit on your self or even give a bonus to a skill attempt roll.
Quote:
The world of Twilight: 2013 is a harsh and unforgiving one.
Most of the planet’s population died in the events of the last three
years. Those who remain had some natural advantage, be it skill,
preparation, or blind luck. Survival points (SPs) represent this
latter quality, giving players a last-ditch mechanism with which to
mitigate the impact of unfavorable die rolls.
