Yes llamas live for a long time, and they have a pretty lucrative market for their wool, plus if you have other animals, sheep or goats the llama will protect them by either spitting on or kicking the living guts out of anything that they perceive as a threat.
I've never met a mean llama, unless they're spooked or think you're a threat, last llama I has contact with would be your best friend for a dog treat, literally walk up and put its head and neck on your shoulders, then again that may have just been a quirk that grummar had.
Guess I'll buy a llama and use the remaining $48 to buy a charger for my new pho-
wait...
