Okay, recently I have become very interested in pupil size.
What got me interested:
1. I have noticed that my pupils are very small. Thus, I am concerned about whether or not this is "good" or "bad."
2. People on certain drugs have changes in pupil size.
For example, people on LSD apparently have very large pupils. However, so do people on MDMA. One supposedly lowers serotonin while the other supposedly raises it. Additionally, a symptom of high serotonin is supposedly sensitivity to light - I can personally attest that if I eat starch or other things that bother my stomach, I will become very sensitive to light. Could this be because it makes pupils larger, thus letting in more light? However, it does seem that people in good health often have larger pupils? Or no?
So what do you know about pupil size? Could small pupils possibly mean low fear? Could large pupils possibly be a sign of good health because of low serotonin? Is serotonin even related in the slightest? Why do girls with large pupils seem to be somewhat more attractive? Is the same true for men, or possibly the opposite? Why do people with very small pupils look kind of untrustworthy?
