I suffered insomnia and felt freaking tired at work. However, I still went for a jog to discharge the "lazy" energy within me, and surprisingly, I managed to complete the 7km route without dropping dead. I must thank God for keeping me healthy and safe all these times - I could have a heart attack while pushing myself when jogging; after all, I'm no longer as fit as I used to be.... Sigh, the side-effect of growing old..... :p
