Weaker

This is year has been a very miserable year for me. I could no longer be able to stay up in the afternoon to study. Now, I'd have naps in the afternoon while my stamina would not permit me to stay awake long enough to compensate the wasted hours at night. I'm baffled. Or perhaps, it's just one of those effects of holidays. My Physics teacher loved to call it as the 'holiday inertia'.
