Biology
Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution. Chris has talked a lot about biology and therefore fails hardest at it. Chris surprisingly accepts biological facts such as evolution and vaccines which many Christians reject though he has the facts jumbled up and ends up speaking nonsense most of the time.
Reproductive biology
One of the most well known fact about Chris is that he drinks his semen, he mixed up his knowledge on the sperm and egg and thinks the sperm count is a fixed number that goes on decreasing every time he nuts, to counter act this supposed decrease he drinks his own semen to make sure he can get 13 year old boys pregnant. He also believes keeping semen inside his refrigerator will keep it viable not knowing the only thing this will do is give him ice cubes to use in his fanta.
Chris also learnt that transgender woman can get periods from a facebook post which is false[1] The only way Chris could have something resembling menses is by ramming medallions up his ass. Abdominal cramps are common for biological women during periods; for MTF women, this is impossible due the lack of a uterus. Feeling under the weather is also a common symptom of perids caused due to changes in hormones released by the female brain and uterus since Chris lacks both a uterus and a brain he is imagining his symptoms.
He also listens to certain audio tracks on youtube which claim to magically help sprout a vagina. After a while of listening to them, he felt up his junk and confused his pubic symphysis for a vulva and sliced open his taint. This not only shows his complete belief in pseudoscience but also proves he has no knowledge of female anatomy.
Neuroscience
Chris rejects the existence of asperger's syndrome though it is a well proven syndrome in the scientific community. He thinks that people with aspergers steal the limelight from people with autism though this doesn't make any sense since both of them are incredibly similar and on the same spectrum. Chris believes that the mind and body are separate entities where the mind can move between different bodies I.e the body is nothing more than a vessel for his mind. This has never been proved and most research points to different inter-neuronal connections being the reason for different personalities.
Immunity
During the COVID-19 pandemic, Chris watched the Cells at work anime and claimed it would boost his immune system, possibly in reference to the theory that immune activity increases after witnessing sickness.
