Its because the caffeine reacts in our brains differently and helps engage pathways in our brain to achieve a semi-neurotypical feedback loop and focus. Its why most adhd meds are stimulants and you'll find unmedicated people have an unhealthy reliance on caffeine.

The science behind why we often seem "lazy" is really interesting.

Try being an inattentive adhd person and weaning yourself off caffeine. It is a true test of pain tolerance lol

Pre screening tests for Australian armed forces at least had a stall with a 2 way mirror on the wall you face.

Its like Joker's or Rick Sanchez's origin story!
