I heard about this theory too but I am not convinced it is solely due to the effect age has on sperm because I see Asperger/autism traits in some of my relatives. It appears to be genetic in my family. My late grandfather had it but was never diagnosed. My father has some traits and so does my first cousin. I am diagnosed.

My dad is 30 years old than me.

I don't know anything about schizophrenia.
