No matter how smart you are, there is one thing you will always overlook, what is it?

Why this works

This riddle plays on the idea of something that is always present but often goes unnoticed—you can think of it as a humorous commentary on human perception. While we may be highly intelligent and aware of our surroundings, our own nose is literally in our field of vision, yet we tend to overlook it because it blends into our daily experience. This clever twist on self-awareness makes the answer both amusing and relatable!
