You knew it, and were just waiting for science to catch up. Coffee is good for you. For your brain. For your health. Overall, it’s the elixir of good health.

Scandinavian researchers followed the health of coffee consumers from middle to old age. The subjects were divided into three groups: low coffee drinker (0-2 cups), moderate (3-5), and heavy (more than 5 cups per day). 21 years later, 1,500 participants were examined for dementia and Alzheimer’s disease. They found that “Moderate coffee drinkers had a 65%-70% decreased risk of dementia and a 62%-64% decreased risk of Alzheimer’s compared with low coffee drinkers.” Low coffee drinkers also scored higher for depression. Coffee drinking has also been associated with lower risk of Type 2 diabetes.

What is it about coffee that has such a salubrious effect on the health? Caffeine? Not quite. Tea, also a highly caffeinated beverage, didn’t produce a similar pattern of mental health in its drinkers. Perhaps it’s something else in the coffee that does it. Whatever it is, you now have a better reason to hang out at the coffee machine at work.

Often overlooked, the side-effects of topical creams is more important than credited. Lidocaine is a topical numbing agent frequently used before mammograms. The cream is spread on the skin and allowed to absorb for 45 minutes. It is also used to dull pain from laser hair removal, or any other surgery covering a large amount of skin. Research studies found no side-effects; however, the clinical trial did not have enough of a sample size to account for rare and unusual side effects.

This became apparent when two women spread lidocaine and tetracaine on their legs, covered it in plastic, and left it for 45 minutes. They experiences seizures, fell into comas, and died.

Experts theorize that broken skin or elevated temperature might have raised the amount of the drug entering the bloodstream to toxic levels.

When using topical analgesic, use the minimum amount, and avoid broken skin.
