I’m sure everyone who’s reading has at one point or another taken a word and repeated it until it lost its meaning. Maybe when you were in elementary school, as a bet to see who could say “rural” or “squirrel” the most times in a row. After a certain point, maybe after 20-30 repetitions, your tongue or concentration fails you (because you are 5 and saw a butterfly or something), and you stop and laugh. But what if you keep going? For 10 minutes, 1 hour, a day? And what if you repeat something...
