I thought my calculator died.

First the LCD wasn't displaying properly, and then it didn't display anything at all.
I bought a new one which cost me $29.90
Out of curiousity, I swapped the batteries, and the old calculator started working again. -_-

First with the IBM chapter 10, then now with the calculators. :/

2nd time in a week, someone has commented that I look pale.
I wonder y is that so. The only thing that I'm doing differently is that I am sleeping 10-12 hrs and by 1am everyday. Probably too much of anything is no good.
