age vs height

A Ram, An Ox and a camel are walking through the desert together when they come across a large very green tuff of grass growing out of the sand.the Ram stated " I should get this tuff of grass for i am the oldest, as i was in the field with the ram that Ibrahim sacrificed instead of his oldest child."the Ox replied "nay then i am the oldest for after Adam was expeled fronm the garden i pulled his plow in the first field he cultivated.the Camal horrified at how his companions were lying he then stated " age is not a good criteria for who should get it, height is." and with that leaned over and ate the grass.
