Orc ages

[ImperatorK]

In what book or where on the SRD can I find orc age categories? Preferably PF. I found the "Adulthood" age, 12 years, but didn't see Middle, Old and Venerable. I'm not playing in Golarion or any other official setting and even if I would I could probably just change it to whatever I want, but still, I like to know the official texts for rules or fluff.

http://paizo.com/pathfinderRPG/prd/advancedRaceGuide/ageHeightWeight.html has the aging effects for orcs further down under "Featured Race Aging Effects."

For an orc, adulthood is 12 followed by middle age at 20, then old at 30, venerable at 40, and death by old age at 40 + 1d20.

For some reason PFSRD doesn't have that. Weird.

Thank you.
