When you have a cold, it seems like you produce more mucous, but the mucous really just changes consistency and becomes thicker and often a different, greenish color.
The reason that the mucous during a cold becomes green later in the course of the cold is because your immune system sends white blood cells called neutrophils rushing to the lining of the nose to try to fight infection. These cells contain a greenish-colored enzyme, and in large numbers they can turn the mucus the same color of green.
Recent research has shown that patients with red hair need larger doses of anesthesia, and that they are resistant to local pain injections.
Red-haired patients have a gene called melanocortin-1 receptor that is different than patient’s with brown, black, or blond hair. This “Mc1R” gene controls pain receptors in the brain.
Because of this genetic difference, redheads require up to 20% more general anesthetic to control their pain during surgery!
Many people worry about whether they drink too much coffee. Some people are sensitive to too much caffeine, and can even get palpitations (irregular heart beats) if they have too much. But has science shown any health benefits from coffee? Here is what studies have shown to date:
- Coffee can lower the risk of Type II Diabetes
- Coffee lowers the risk of Alzheimer’s and Parkinson’s Disease
- Coffee can help prevent Cirrhosis of the liver for those who have 4 cups a day
- One cup of coffee has Vitamin B1 (thiamine) B3 (niacin), B2 (riboflavin), B5 (pantothenic acid), many antioxidants, potassium and manganese!
Every year, 200,000 people in the United States will contract the flu. About 30,000 people die from the flu a year in the United States, which is about the same number that die from motor vehicle accidents. In 1918, the “Spanish” flu caused 20 million deaths worldwide.
The word influenza comes from the Italian word for “influence”, because it was believed that the planets, stars and moon influenced the timing of the flu season.
If someone who has the flu sneezes on a table or hard surface, the virus can live between 2-8 hours.
The economic cost of the flu in the United States per year is $8.4 billion in lost worker productivity.
Getting the flu shot reduces your chance of getting the flu by 50-60%. And you can’t get the flu from the flu shot!

Appendicitis as you know is a very common condition. Over 300,000 appendectomies are performed in the United States every year!
The first appendectomy, or removal of the appendix, didn’t happen until 1735. A London surgeon successful removed the perforated appendix of an 11-year-old boy. The boy made a quick recovery (for those days), and was successfully discharged from the hospital in a month!
Twelve percent of men and seven percent of women will get a kidney stone in their lifetime. Your chance of having a kidney stone doubles if you have a family member who has had one. The average kidney stone is about 5 mm (0.2 inches). Most kidney stones will pass on their own, but some need to be removed. The biggest kidney stone on record, which had to be surgically removed, was 2.5 pounds!
