Bruh no it ain't it's how the body works
You seriously tried to invoke a God of Gaps fallacy for something we understand, also I was saying the hand cramp thing just cause if I remember
I assume because everyone if they write for long enough starts having pain, I don't know exactly but it's scientifically explainable so you literally just took the God of Gaps fallacy which is saying God for unknown stuff and using it but with known stuff
