There is so much information I have not mentioned. . . books worth of research. The data includes making adjustments for outside influences.

Sure, you might have "angry" lines from squinting from the sun. It's important to not just dismiss them because you don't like what they say about you, but to ask yourself very pragmatically, "am I angry or just sun-tortured?"

If sun tortured, then wear a bigger hat and darker shades.
