I got a letter from an MIT student today. She said she had tagged some carbon atoms with trackers and had been following them. She told me one was now part of me. She said they had originally tagged my carbon atom on a beach in Alaska. After they tagged it, it had been washed into the sea by the rain. Then it was swallowed by a Humpback Whale. The whale was pretty old and it died. It was eaten by a tuna. The tuna got caught in a net off the coast of Japan. It ended up in a restaurant in Portsmouth. That's how it got to me. It feels pretty neat to be a part of all that. It got me thinking about how it all started with you and dad. Just wanted to write and say thanks.
