Why does the colour of urine vary from light to bright yellow when we do not drink water for a long time?Some people have waaay too much free time on their hands.
Come to think of it, maybe not as much time as the bozos at the paper who have actually decided to take this question seriously and have wasted about eight inches of newsprint to answer it. I didn't bother to read the answer, but I can guess it probably has to do with the chemical changes in one's body as one sits and thinks of idiotic questions to pose to newspapers' science desks.
