Jay Chou's An Jing - Saxophone & Piano Instrumental

Yawnz. I've been yawning non-stop since I woke up at 11.30 this morning. I absolutely do not have a single impression why I cant stop yawning. I never cease to feel exhausted, physically drained, weary, fatigued, worn etc. You get the idea. Yawnz.

Honestly, is there really something wrong with me? My mind or my body? Or both? Yawnz. Help anyone?
