Well, as you know, Vietnamese has a proverb that our health is very important. It's more important than money and it's like gold. Personally, I also agree that health is more important than money because of the following reasons:

Firstly, if we aren't healthy, we can't do anthing. If we don't have health, the children can't play or study and the adult can't go to work. We'll feel tired all day and it's very bored if we just sit and can't do anything.

Secondly, if we are sick and weak (unhealthy), we have to go to see the doctor and maybe we have to stay in the hospital all day if we have serious diseas.

In conclusion, our health is very important. We have to keep us to stay healthy by doing morning exercise regularly, eat healthy food, ... I would argue that our health is the best and it's more important than money.
