I was cramming through a list of 3,500 of the most common Russian words that somebody posted on this site. While I was taking a break between my studies, I found this article on the internet. Apparently, some 59 year old guy in Japan memorized Pi to the 83,431st digit. Wow!

That is a very impressive feat. Of course I am not going to pursue such a useless feat. But if someone can learn 83,431 totally useless digits which have no context, or meaning, then for sure, learning a mere 3,500 Russian words should be a piece of cake.
