Which snaffle bit is best for sensitive mouths?
There are 3 types of materials used in a fire extinguisher, water, foam and pure CO2. The water puts out fire by removing heat. Foam smothers the fire by not allowing it to come in the air. CO2 is heavier than oxygen gas and helps to displace the oxygen molecules from the surface of the burning material.
Personally, I don't see the need for a doctors note on this one, but since you seem to really want one, here is the note I would write for you (since I don't know your name, I'll use the name John Smith as an example): John Smith requires the use of a protective visor while playing in his games. This will prevent any damage that could possibly be done to his eyes with a possible facemask or just simply a straight hand to the face. Mr. Smith is a great player and it would not benefit your team if he had to sit out because his eye was gouged out by an offensive player or defensive player. I would strongly advise you permitting him the use of a protective visor. Signed, Doctor Tremor D. PhD Hope I helped you out
