Easily lazy load another page simply by adding a shortcode with its url.
The 2nd page wont load until the user scrolls to the bottom, than an ajax request is sent to get the page content. 
This can help speed up large pages on your site, by not loading the stuff users don’t see until they scroll down closer to the bottom.
