1: Can you describe "mental health" in a simple term?
2: Sure. I think mental health is basically emotional balanced or a healthy brain.
1: Is mental health important?
3: No. I think physical health is more important.
2: How can you be physically healthy if you are not mentally healthy in the first place?
3: Well. I don't know.
