Yes it's somewhat disheartening for those raised on illusions of our scientific supremacy to discover that we understand very little about the human body or how to correct its defects or failures. The illusion is quickly punctured once you start having any medical problems. The vast majority of the time the answer is "we don't know what it is, but it will probably get better on its own" or "we know what it is, but it's not going to get better and there's nothing we can do about it."
