Did you do the test in print or cursive? I'm working on my cursive again after years of very little handwriting. I've found that, though cursive takes more patience with the motor skills and hand to brain connections, it's easier on the hand.
I've found that a hybrid between print and cursive works best for me in most cases. That said, it becomes "cursive" if I wanna go faster, which also makes my writing progressively illegible lol
I'm the same but I also get an indentation on the last knuckle of my middle finger from where the pen rests. For exams I end up having to take a 5 minute break after each question to recuperate and massage it back to normal.
I just love the way your thoughts have little barrier to the medium and your thoughts and feelings affect the way the ink goes on the paper. I really like to write, and this meme is true. It doubly sucks now that my joints are trash.
