I really couldn&#x27;t agree with this more. Reading before you sleep is <i>so important</i> to getting a good night&#x27;s rest. Using a physical book or an e-ink screen, anything that doesn&#x27;t emit light itself.<p>Seriously, invest $150 into getting a good e-reader, if you don&#x27;t have one already. It&#x27;s well worth the sleep benefits, potentially even more than a good mattress (for a programmer, anyway).
