Life is just a game. From the moment you were born, you have only one life and no you cannot eat mushrooms or collect coins to get extra lives. You only have one. Though you can eat mushrooms to grow bigger and collect coins to get richer.
Life is just like a game of Super Mario isn't it? Full of villians and obstacles. Sigh.
If you're stuck in life, just hit the restart button.
