Have you ever experienced the feeling when you feel absolutely powerless to do anything? It usually comes at weekends and stays till Monday morning. Yeah, we are sure you've already recognized what kind of illness we are talking about! And guess what? We've found out what kind of disease it is and where it comes from. All of a sudden we found a video from a Chinese zoo featuring a tiny panda cub trying to fight with this strange syndrom. So don't blame yourself for being lazy - you simply get ill for a while and this illness will vanish as soon as you go to work!
