live plants

I don’t know if you believe this but I heard it from one of my friend that we need to put live plants inside to our house. She said if somebody is sick that lives to your house the disease will go to the plants. That is why she said that people who have a lot of live plants in their homes live longer. I am not sure if that is true because I really don’t believe any superstitious beliefs. But as for what they said you have nothing to lose if you believe.
