The nose ring is pretty much necessary. Bulls (in general and I assume for yaks its the same thing) lose their respect for humans the older they get. It can then happen, that they try to attack a human to demonstrate, that they are stronger (which they are). In this case this nose ring is the only way you can save yourself. Grab the ring, turn it and suddenly a raging bull turns into a quite submissive animal.
