Went to the beach for the day and wrote as much as I could about this incredible experience and where my life seemed to be taking me, etc. I fell asleep, and when I woke up the papers were blowing down the beach and into the water. I sat up and watched until I couldn't see one piece of paper left. I drove home and felt happy.
Obviously, the characters have no real showering system on the island... I think I've only changed (clothing), like, three times on the island. We're stinky, but we live with it. It's part of the charm of the Lost cast. You bring visitors on set, and they're very excited to see everyone - until they get within three or four feet. Then they realize we all stink.
