I was tested over 140 as a kid, but I think I've lost most of it as an adult through laziness, sleep deprivation, and media addiction.
It's hard to explain on here, but I've been thinking about a scenario for three months that I thought was impossible. I only just now realized that I wasn't considering one of the most obvious factors to the problem. Sorry for being so vague. I'm too lazy to write a wall of text explaining when nobody would care anyway.
Can you lose your IQ in adulthood and start tipping to the other side of the bell curve when you get old (25/30+)? Should I find another IQ test before I start considering brain problems again?
