饮水益健康

I read that the life expectancy of people in a small village near the Blue Mountains is up to 88. That's really high!

Do you know the reason?

I have no idea.

I think that it has something to do with water they drink everyday.

In that way, we can do some research about the water to solve the mystery.

Yes, and let people from other places drink the water, so that others can live just as long as them.

Good idea!
