Conditions all go their own natural way.
Whether we laugh or cry over them, they just go their own way. And there is no knowledge of science which can prevent this natural course of things. You may get a dentist to look at your teeth, but even if they can fix them, they still finally go their natural way. Eventually even the dentist has the same trouble.
Everything falls apart in the end.
