You now and you 10 seconds ago share lots of things, like body, location, certain impulses from hunger or the senses, but most importantly a shared history. Our stream of consciousness isn't built from one long string of thinking, but many connected but dissectable instances, each one a new person born from the contributions of the last "person" to inhabit this body. In essence, you are many people. When you live in the moment, you accept and live fully for your 10 seconds of fame.
