About a year or 2 ago, I used to inhale lighter fluid. I didn't know what I was doing back then and now I'm really really regreting it. I love my body. I also saw few articles, that people had died because of doing that. I'm sure I killed some brain cells back then, but can they be healed? I don't really think I have any big memory or concentration problems. I only think I have, but I can't really roll time back and compare. I don't know anymore is it normal to be like that? Sometimes, when I'm watching movies, I lose the point while reading subtitles. Is this also normal?
