Biorhythms

I have this project in my pre cal class due friday.
I'm stressing, but I know it's going to be awesome.
I love the theory.
It is theorized that our bodies, minds, and emotions undergo a cycle.
Represented by a sine function that period repeats and repeats and repeats until you stop living.
It's fascinating.
It seems everything that illogical, biased, and uncontrollable has a root or a cause.
The high points of the sine function represent the best, or the highs of one's activity.
The low points represent the sleepy, or the inactive days of one's cycle.
The "bad days" in one's cycle are days that occur when the graph crosses the x axis.
The theory is not perfect.
It doesn't apply to everyone.
But, I believe it's about right with me.
I think it may affect teenagers, more than adults.
That week is was depressed, I was coming down to a critical point.
I felt sick last night, and that was on a physical low day.
It may be an answer to my random feelings.
On critical days, I just won't blog.
