First the sleep. I know that my ideal amount of sleep is 8-9 hours a night, but I react very differently if I get less than that. Handy breakdown:
>10: Kinda sluggish for a few hours. There is in fact such a thing as too much sleep, I guess.

8-9: Morning tiredness I can shrug off within the hour.
6-8: My morning kinda sucks, but by afternoon I'm okay.
4-6: Here it gets weird. Either I'm just dragging a bit well into the afternoon, or I'm REALLY tired but I shrug it off by 1 or 2. No rhyme or reason.
2-4: And THIS is where I was today. I'm generally massively tired at this point, BUT -- like what happened today -- sometimes I'm strangely extra hyper and it cancels out the tired. Then I'm fine for most of the day. It's only now at 8:30 PM that I'm starting to crash. I don't understand my own brain sometimes.
The other mystery of the day is my phone battery indicator. It's the type that has 0-5 bars filled in, which in theory are evenly spaced. In practice, it seems more like this:
5 bars: >20% battery
4 bars: 15-19%
3 bars: 10-14%
2 bars: 8-9%
1 bar: 6-7%
0 bars (OMG FEED ME): <5%
Seriously. I can go several days without charging my phone or seeing the indicator change. But once it dips to 4 or 3, I know I have about 8 hours to charge it. I tested this morning, and 5 minutes of charging got it from 0 to 3 bars. 10 minutes of use brought it back to 0. Why even have those levels there?
