<h1>A comparison between the average world life expectancy and that in the UK, 1960-2013</h1>

<p>The <strong style="color: steelblue;">UK</strong> and <strong style="color: red;">rest of the world</strong> average life expectancy, 1960-2013.</p>

<p>Life expectancy at birth indicates the number of years a newborn infant would live if prevailing patterns of mortality at the time of its birth were to stay the same throughout its life.</p>
