Using Events to Improve Bounce Rate in Google Analytics

The bounce rate cited by Google Analytics for this blog has always been high and it's been discouraging.  Having a high bounce rate is bad, right?  Or does that mean someone found what they needed and left, which would be a win?  I'm not sure, but I was recently told that some people use event tracking to find a truer bounce rate.  If a user scrolls or clicks on something, that shouldn't be a bounce, right?  They're certainly interacting with the page!  With my redesign, I implemented this:

function removeEvents() {
	document.body.removeEventListener('click', sendInteractionEvent);
	window.removeEventListener('scroll', sendInteractionEvent);
}

function sendInteractionEvent() {
	ga('send', 'event', 'Page Interaction');
	removeEvents();
}

document.body.addEventListener('click', sendInteractionEvent);
window.addEventListener('scroll', sendInteractionEvent);

After adding this code, my bounce rate went down dramatically.  Tracking an event isn't gaming the system so I find this situation a bit odd.  Why does tracking an event, not firing a pageview, affect the bounce rate so much?  I'm not sure, maybe you can tell me!

Preventing Events from Affecting Bounce Rate

Let's say you don't want events to affect your bounce rate; you can use the following to do so:

ga('set', 'nonInteraction', true);

It's odd to me that an event would effect bounce rate, if the definition of a bounce rate is a user going to your site and immediately leaving. A pageview is not an event so....weird!
