Why Writing by Hand Boosts Your Brain and Prevents Writer's Cramp
Writing by Hand is Good for your Brain

After twenty-five years of composing books with a fountain pen, I can confirm that writing by hand engages more of your brain without causing writer's cramp. The secret lies in using the right tools: fountain pens or rollerballs on paper with just enough friction, combined with cursive writing. Unlike typing or using styluses on glass, this analog approach balances physical effort and mental flow, making it ideal for deep work.
Relying on a little bit of friction reduces the amount of mental and physical effort, whereas removing it entirely makes the process more tiring.
