I would add, you've only one set of ears as well. Protect your hearing or you will be deaf or worse: deaf and suffering tinnitus!Eye protection, you’ve only one set.
Hearing loss is gradual so you won't notice it like you would a stick in your eye, so you usually won't notice after it's too late.
Tinnitus... I may offer lifelong tinnitus as a curse for enemies. Avoid at every PPE cost!
