Wait 'til you're 50.
You'll have no problem crawling out of bed ... because your bladder will feel like it's about to explode. And, prior to waking, what do you think your dreams will be about? Waterfalls are not always a beautiful, nor welcome, metaphor. You sit down to write a poem and the first verb that comes to mind is, 'piss' ... which is generally unhelpful if the poem is meant to be a client's advertisement.
We'll see what you consider a "cantankerous malfeasance" then. :-)
