canlı türüne göre değişkenlik gösteren durumdur. insanlarda 16-21'dir, keçilerde ise onlar durana kadardır. danny isimli keçinin sözlerine kulak verelim isterseniz;

"I never learned to rap, always knew how
Ever since a n*a eight, knew what I would do now
When I turned twenty-eight, they like, "What you gon' do now?"
And now a n*a thirty, so I don't think they heard me
That the last ten years, I been so fucking stressed
Tears in my eyes, let me get this off my chest
The thoughts of no success got a n*a chasing death
Doin' all these drugs, hope an OD ain't next, triple-X"
