More people are turning to the internet for self-diagnosis of health problems. This is one of the great benefits of the technological marvel that is the world wide web, and not only do I fully support it but I wish to contribute myself.
This is why I am sharing a system I developed to accurately pin-point your health problems using a cheap and easily accessible tool: BEER.
This is how it works: your body is a complex mechanism that processes inputs to generate energy and provide the nutrients that your body needs to operate, while expelling anything that is not needed. If your body is not operating effectively, it will expel more of one thing or less of another, and there will be tell-tale signs of this in the colour of your pee. Stick with me here ...
To take advantage of this underrated bodily function, I have developed the Perfect Urine Beer Scale (PUBS). Using PUBS, you can tell what ails you simply by comparing the colour of your pee to the colour of an ale from your local beer store.
The PUBS© diagnosis
If your pee looks like: COORS LIGHT
Diagnosis: The pale colour indicates that you are lacking vitamins and minerals in your diet. Go buy yourself some fruits and vegetables for a change. If your diet consists mainly of Coors Light and empty carbs, your urine will look like Coors Light. Coincidentally, your pee and Coors Light also probably taste the same.

Diagnosis: You are healthy. This is a normal colour, which means that your body is operating normally so you can cancel your doctor's appointment. There is no need for you to waste his time and yours with a needless check-up when you can tell just by looking in the toilet bowl that you're in perfect health.
If your pee looks like: RICKARD'S RED
Diagnosis: The red tinge is a result of blood in your urine. You had better sit down for this part ... you are dying of cancer. If you haven't caught it by the time you start to pee blood then it is probably way too late. You shouldn't have cancelled that doctor's appointment last year. What were you thinking?

If your pee looks like: SLEEMAN HONEY BROWN
Diagnosis: This is darker than normal which indicates that you are dehydrated. The solution is to drink more fluids. No, NO, not BEER. I mean something besides beer. Get a glass of water or juice or something like that.
If your pee looks like: NEWCASTLE
Diagnosis: You are extremely dehydrated. What the hell were you doing? Never mind ... just find a cool room, perhaps a rec room in the basement, drink water and keep drinking until your pee returns to normal. Do it now, before you pass out and require an IV drip.
If you pee looks like: HOEGAARDEN
Diagnosis: The cloudy appearance is due to a kidney infection called pyelonephritis. It sounds bad, but don't worry, it is treatable with antibiotics although severe cases may require hospitalization.
Or you may have cataracts. Better get your eyes checked too.
If your pee looks like: GUINNESS
Diagnosis: You are a zombie. That is all you need to know.
Disclaimer: The accuracy of the PUBS© diagnosis may be compromised by eating Doritos chips with artificial colouring, especially Spicy Chipotle BBQ. Also, everything else may be grievously incorrect.
