My question is what is the average lifespan of the Mur-Po?

The average male or female Mur-Po will usually live to around two hundred years, though many die in combat earlier than that; however, it is not unheard of to see certain Mur-Po live to two hundred and fifty or even three hundred, depending on their lifestyles. So, generally, between two hundred and three hundred is the average lifespan. 

The neuter sex, however, is much shorter lived, usually dying between thirty and forty years of age, but this is due to the pangs of the many births they bring to term in their lifetimes, and their general living conditions. They are generally more or less brain dead, although their sexual organs and motor process function as per normal.
