https://pubmed.ncbi.nlm.nih.gov/21957440/ https://pubmed.ncbi.nlm.nih.gov/21957440/ Toxoplasma affects dopamine metabolism - body starts to produce more of it. Dopamine is also released with alcohol intake, notice that alcohol also makes everyone more confident, attractive and, well, prone to car accidents. I guess the "rough childhood" also has something to do with alcohol or other drugs somehow, that means dopamine metabolism is also affected. Dopamine is a powerful thing.
