“Typically, the sense of touch is so omnipresent, and its effects so seemingly ephemeral, that it is often taken for granted or overlooked. We now know that its effects linger in the brain long after the sensory experience ends, and often without our being directly aware of it. Surprisingly large amounts of information are preserved as well. As such, a single touch has a far greater impact on the mind than one might have ever imagined—which makes the act of doing so all the more powerful.” — Scientific American
