which one is correct "stay health" or "stay healthy"
I saw a sentence in my textbook---Staying healthy is important. There are three main things we can do to stay health.
1. So I wondering which one is correct, 1."stay health" or 2."stay healthy".
I know 2."stay healthy" is correct, because [stay + adjective is a common usage], but how about 1."stay health" ?
2. If both are right, and you can help me to figure out what is the difference between "stay health/healthy", it will be really appreciated.
