I get what you mean… though, I feel like an IQ test is a biased test, I took one as a teenager and scored high. Which was a morale boost at the time, but a few months later I had medical problems and ended up having a stroke and had to basically start all over with speech, motor and memory.
Sure, I survived. But I went through every therapy, started back up and realized I wasn’t close to what I was before. Which was crushing, sure I knew it wouldn’t be the same and I’m still above average, but the latent memories of my capabilities before constantly haunt me.
I didn’t mean to depress anyone, just enjoy the blue zone if at all possible. I constantly try remembering, it can get worse. /hug
