You know how the ancient Chinese came up with yin, yang, 5 element theory, and all that? They took observations from the world and adapted it to the human body. We can do that, too.

There are over 4,000 miles of pipes under Dallas, with diameters from 2″ to 5′. Sometimes people pour grease down the sink or something and are lucky enough that it flushes out of their personal plumbing. Then it sticks to a pipe farther on down the line, which gets clogged and bursts from the pressure backed up in it, and it’s a big mess.

There are over 60,000 miles of blood vessels in the human body. The diameters range from 8 μm to an inch. Sometimes stuff sticks to the sides of the vessels, and blood can’t get through, and it’s a big mess. Without blood, there is no exchange of oxygen and waste products, and without oxygen, tissue dies. Which is pretty darn bad if that tissue is brain or heart. Still not impressed? There’s a lot of blood vessels in your junk. Yeah, I said it; general health has everything to do with sexual function.

For both of these systems, the primary thing is to not dump in stuff that clogs it. That would be saturated fats (though in the case of the city pipes, the liquid stuff has to be processed out of the wastewater, too, not a cheap or easy prospect), which are solid at room temperature. Don’t cook? Read labels.

The human body has some other factors to consider. It is always going to have some fat in its composition. Some conditions, like diabetes, obesity, low activity, and hypertension, are going to make the body more likely to have fat fall out of the blood and onto the arterial walls. This is why you should get regular exercise, not smoke, and eat a balanced diet.

Ever take Organic Chemistry? Ochem labs are all about isolating stuff and weighing your product. One time we had to isolate cholesterol. And we forgot to weigh the empty test tube. We were running out of time, and I was running out of steam; scrubbing with soap and hot water was not getting that tube clean. The TA suggested ethanol. One little splash, and that tube was empty! So, I am a firm believer in having a little drink now and then to benefit your heart. Thing is, though, the human body isn’t made of lab glassware, and there is still going to be liver damage and stuff if it needs to process too much alcohol. The guidelines are 1-2 drinks daily for men, and 1 for women.
