It has been a slow day in the medical clinic. So far, you've treated a series of coughs and colds interspersed with regular checkups of patients with diabetes, hypertension, and dyslipidemia.

Your next patient walks in: a rather stocky man who looks exhausted. He slumps down in the chair; you introduce yourself and ask how you can help him. He runs his palm over his face and then begins:

"Nice to meet you, Doctor. My name is Joss and I'm 62. My wife dragged me here. She says that I snore really loud every night and that she can't sleep. It was either sleeping on the couch or coming here, so here I am."
