"Vegetative" State?

Did you see this article the other day about a woman in a so-called "persistive vegetative state"? Her mother, who is her caregiver, said she has come out of the coma before. It must be really hard to have her slip back into it after three days. But what a consolation it must have been to her mother, daughter and grandchildren to have her come out of it, even for awhile, and say, "I'm fine." There are certainly mysteries in life. But one thing we don't have to be puzzled about is that human life is very precious!
