This podcast has been a great relief to me. Recently my little brother showed me this set of rocks he had for his science class. I thought "Oh this is great! I get to taste all these different rocks side by side." So I proceeded to try all twelve types of rock. Guess what I discovered. They all taste the same. I could detect no difference between flint and limestone or any other combination. They all taste like rock. At the time I thought there was something wrong with me. Like I lacked the physical ability to detect the subtle nuances between the rocks. Thank you for letting me relax a little.
