Your eyes have “immune privilege” meaning your immune system effectively does not know they exist as it would attack them and make you go blind if it did.
Meaning, if you ever get a cut in your eye, go to the doctor, or else you’ll lose the eye.
I was in the Army, and stabbed myself in the eye with so. Many. Branches. So much damage.
That was decades ago, and I’m not blind yet… what’s the point at which it becomes a danger?
If your immune system discovers your testicles you’ll go blind? Is that what happens if you masturbate too much?
