Answer:
I love spinach.
When young I am sweet in the sun. When middle-aged I make you gay. When old I am valued more than ever.
Who makes it, has no need of it. Who buys it, has no use for it. Who uses it, can't see it. What is it?
My first is a heir; My second's a snare; my whole is the offspring of fancy; which I sent out of play upon Valentine's day As a token of love to my Nancy.
