Well... Life's not fair

How is it fair that the girl the goes to bed at 10 (ok, 10:30) almost every night and gets about 8 hours of sleep every night ends up sick while the girl that stays up burning the candle at both ends (as Gramps would say) doesn't?

You remember what your parents used to tell you when you complained that something wasn't fair: Well... life's just not fair; get used to it.

Here I am, 23 years old, and I still complain about how unfair the world is. And the truth is, I'm going to keep complaining about it, probably forever. All I can tell you is: Well... life should be fair; get used to it.

On a somewhat related but mostly not side note: how is it possible that I will be graduating with my degree, in chemistry, in less than a year, and I still don't know which one is the anode and which one is the cathode?
