We’ve covered shoes in Book 1 and tactile boundaries in Book 2. Now, it’s time for the "Main Course." Whether you’re a corporate shark or a first-time tourist, if you value your curd-rice and your green chilies, this is your biography.

In this book, I explore the hilarious (and occasionally horrifying) reality of our need to poke the artifacts of the world. I’ve seen C-suite executives—men who manage billion-dollar portfolios—secretly trying to see if the marble on a Renaissance statue feels like real skin. I’ve seen families in London museums trying to "test the quality" of ancient Egyptian linen.
