The song says “Don’t go chasing waterfalls”.

What does this mean? What is being conveyed by this metaphor? Waterfalls are stationary even though the water passing over them is moving. You can’t chase a waterfall any more than you can chase a hillock or a pond.

Niagara falls has receded. Over the last 12,000 to 12,500 years, the falls have retreated roughly 11 kilometers. Sure it would be a slow chase, but still.
