Lifespan

Lifespan is a Property that is visible in the Basic Stats & Backgrounds (Window). 
See also Lifespan's Property definition: Property/Lifespan
It measures how much time a Character has to live. Once Age exceeds Lifespan (or lifespan falls below age) the character will die. Lifespan can be used to cast certain Miracles and can be increased through Manuals, Medicines, and Pills. Characters will age at one year per year (112 days), unless modified by certain Manuals, meditating on certain Boss drops, or going to the Heavenly Battlefield. Exhausted characters will start with a low lifespan.
The closer a character's age is to their lifespan, the older they look. (ie: a 24 year old with 27 lifespan granny). The further away it is, the more baby-faced they look (ie: a 100 year old character with 2000 lifespan). A character will receive a negative Moodlet if they are about to die of old age. It goes away when their lifespan increases.
==Tribulation==
Cultivators with 1000 or more years of Age may choose to perform a Lifespan Tribulation. Defeating this type of Tribulation will bestow a sub-spirit to the Cultivator and increase their Lifespan by 100 * defeated Lifespan Tribulations. Each repeat of this type of tribulation will result in its strength doubling, up to a maximum of 1 billion Qi.A cultivator may not perform this indefinitely, as Lifespan is capped at 9999 due to its Property definition. 
==Pills==
Many of these Pills can be improved by using Specter Refinement to upgrade Medicine Strength. 
All of the Pills which increase Lifespan have an 80% Medicine Resistance, so taking them more than once gives very diminishing returns. Also, taking the stronger lifespan-reducing pills without increasing Lifespan first with another method will instantly kill the cultivator from loss of Lifespan.
