Does tying yarn around your finger help your memory?
It was only used because it reminded people that there was something to be remembered. Otherwise no, it does not actually improve your memory.
Wow... If you tie it tight enough, youll lose your memory or faint
Sure! it reminds you at least to take the yarn off before your fingertip drops off from not getting enough blood circulation.
Sometimes. but when you do that, sometimes you only remember that you have something to remember, and not what you were supposed to remember.
