Answer:
I am a mountain at night meadow at day
I have married many woman but has never been married
I am easy to see but no one likes looking at me. Without me there would be no you. I can make you complain or make you happy. But you almost always take me for-granted.
I'm very tempting so its said I have a shiny coat of red and my flesh is white beneath. I smell so sweet taste good to eat and help to guard your teeth.
I am mother and father, but never give birth or nurse. I'm rarely still, but I never wander. What am I?
Almost everyone needs it, asks for it, gives it. But almost nobody takes it.
