Finally....

Two days torturing exam ends finally. I couldn't believe that I could still able to clean up my house after two tiring days. The very tough na na was gone. Remember those old days, once I said I can do it, I make it. But this time, I failed. I failed to keep my study mood. I failed to concentrate. I seems no long to have my super short term memory and also my clear mind. Why's that? Am I aging?
