My Dad was a physician, and I remember as a boy he could closely diagnose illnesses by smelling people. My Dad would smell people who had wounds that would not heal. The prime candidates were people who smelled of sweetness. The infection called gangrene produced a sweet smell, and if you smelled sweet, it was likely you would lose a limb. I do not believe medical schools today introduce medical-school students to such science.
There is an article in Mind. Scientific American about how different diseases are diagnosed via the nose.

When I was in the US Army, every meal was served with cold Iced Tea. If you wanted water with your meals, you had to make a request to the main cook, so I drank sweeten ice tea against my will. I no longer drink ice tea.
Scientists have discovered that green, black, and oolong teas brewed from tea leaves protects against cognitive decline. Ice teas sold in bottles in the supermarket do not provide cognitive benefits. To read the story reported in Laboratory Equipment, visit Google and type: "Daily Consumption of Tea Protects Against Cognitive Decline."
I have had 5 operations in 10 years due to bad and malignant tumors. I asked the surgeon the types of anesthesia used on me during an operation. Several brand names of anesthesia are used depending on their properties and less expense to the patient. Many people do not know a second anesthesia is administered that locks your muscles so the patient cannot move around during an operation. The human body produces a sort-of anesthesia during REM sleep that locks your muscles. I remember I use to watch my brother's eyes move about under his eyelids during REM sleep. It was very hard to awaken him during his REM sleep-cycle. Go to Google and type the title of the research paper into the search box: "Neurons Paralyze Motor Function During REM Sleep."
I have been a poor sleeper for 20 years. I receive about 4-5 hours of sleep each night that leaves me somewhat tired and sleepy the following day. I love the feeling of short naps if taken in the morning-time. Naps in the afternoon makes it hard for me to fall asleep at night.
A researcher has discovered a sleep-gene that I hope I may have. I just sent a sample of my saliva to a genetic-testing laboratory in Oregon to test my genes for malignancy that cause Alzheimer's and tumors. The designation of the gene is called "ApoE, " and tests cost about $200 at Life Extension Foundation(lef.org). I shall let you know the results of the genetic test in about 4-5 weeks.
