I must have exercised too much recently because my back hurts where my old injury is.
In the morning before going to gym, it hurts a little. After gym, the pain doubled. 

I'm already behaving like an old lady. With a body seemingly full of defects, even I'm only just slightly older than a quarter of a century? Haha..
Anyway, now at 1.27am, preparation for my strategy exam case study is testing my endurance to keep awake..  

Really tired.. Arghhh...
