ok so your working and your brain looses focus because your mum walks in or some shit
idk why your brain is gonna loose focus but i can guarantee it will happen at least once
but here is what you should do
look up
im not retarded i promise
im only autistic
but if you keep your head straight and look straight up for about 30 seconds
it pretty much resets your focus and gives you sudden alretness
but remember after you do look up your brain and eyes will be a little fuzzy
but thats good because now you have created a bigger distraction than what distracted you
and the best part if that this new distraction is temporary so it gives you room to focus on your task again and recouperate
so yeah look up
and if your still confused just search up ahegao face then go to images and then you will see some examples of people looking up lol
dont actually do it and if you do just know you were warned
