Happy Birthday to me! =D I thought I'd have several easy riddles this time since it's my Birthday. :3
Riddle #1 : What get shorter the longer it grows?
Riddle #2: Hardly a day passes without seeing me. I am disposable but not easy to replace. Sometimes I become a source of knowledge. Sometimes I become more powerful than a man. Sometimes I am more valuable than gold, while at other times I am more worthless than sand. Who am I?
