Riddle: My first four letters describe all living things. My last five letters are another word for a knight. My job is to save you, and I'm a fan of water. Who am I?
Riddle: I am as light as a feather, yet the strongest of men cannot hold me for more than a minute. I am with you from the day you are born to the day you die. I can be as putrid as onions and garlic, yet as pleasant as freshly picked roses. What am I?
