I'm dark-haired, lanky, and occasionally socially awkward, but only occasionally. I don't know my exact height or weight. I have brown eyes, a narrow face, thick eyebrows, and facial hair. I have pale skin; rarely do I expose myself to sunlight or the outdoors. I tend to eat food at unusual times of day and night. I almost never exercise. I'm very skinny. I tend to stay up late at night. I'm writing this at 2:05 a.m.

As for my personality, who am I?
Well, hmm. That question doesn't have an answer.
I'm a collection of neurons, chemicals, and molecules that form emotions, intuition, memories, and the illusion of experience.
Is this real? Define real.

I seem to be a human organism that gives the appearance of life.

Who are you?
