INPUT ARTICLE: Article: Many products that people consume in the morning contain caffeine. If you have decided to eliminate caffeine, you need to be able to identify products with caffeine. Common caffeine products are coffee, soda, caffeinated teas, energy drinks, and chocolate. Be careful not to consume products with hidden caffeine. This includes energy bars, non-cola sodas, decaffeinated coffee, coffee-flavored dairy products, and chocolate candy products. Caffeine can affect different people differently. Many of the effects of coffee are positive. Caffeine is a mild stimulant and has been linked to a number of benefits, including decreasing the risk of Type 2 diabetes and Alzheimer's disease. Moderate coffee drinking (about two to five cups a day) has also been linked to reducing the risk of gallstones, colon cancer, and Parkinson's disease. Moderate coffee drinking can also help with cognitive and memory issues. Caffeine can interfere with sleep, which can cause insomnia or exacerbate pre-existing sleep problems. In addition, for some, caffeine can increase anxiety, nervousness, irritability, and depression. Espresso can increase the blood level of cholesterol. In some people, coffee can slightly increase the risk of heart disease and increase the heart rate. These negative effects tend to occur in people who have excessive amounts of caffeine, such as more than five or six cups of coffee a day a day.

SUMMARY: Watch for caffeine in common products. Learn the positive side effects of caffeine. Recognize the negative side effects of caffeine.

In one sentence, describe what the following article is about: Macro analysis has its basis in the large (Macro) tendencies observed in the economy. Your goal is to understand how major forces are affecting the performance of the economy. Then, base your investment decisions on your findings. For example, if the economy is performing poorly (inflation and unemployment are high while national output is low), avoid overpaying for stocks and be sure to diversify your stocks. The most important macro indicators include: GDP (gross domestic product), CPI (consumer price indices), PPI (producer price indices), unemployment rate, interest rates (Fed Funds, prime rate, etc.), inflation rate, and balance of trade. You can either download the historical data to Excel or access an interactive graph using online tools. Go to the websites of the Bureau of Economic Analysis (http://www.bea.gov/) or the Bureau of Labor Statistics (http://www.bls.gov/) to access the data. Look for the general direction that the numbers are moving in and any patterns that may emerge. Take into account: the historical data you found, current data, and news. The website will have a separate series of data already converted to percent for either Year over Year or Quarter over Quarter. If not, you can determine the percentage of change for an indicator. For example, divide the nominal GDP (in numbers) of one year by the value from the previous year. This gives you the GDP growth percentage for Year over Year. Investing in a broad based stock or stock alternative might be the most convenient with this method of analysis. Select a group of stocks that reflect the movement of the broader economy and track an index like the Dow Jones Industrial average or S&P 500. This approach allows you to enjoy the growth of stocks in the US in general without risking all your money on one or just a few stocks. Understand that macro analysis doesn't specifically help you decide which individual stocks to buy. Instead, it simply lets you understand the performance of the economy. For example, you may want to buy stocks when you think the economy will improve and sell when you think it will deteriorate.
Summary: Understand how macro analysis works. Gather data or access a graph. Observe and interpret the data. Pick your stocks.

Pi, it turns out, also has a place in an interesting thought experiment called Buffon's Needle Problem, which seeks to determine the likelihood that randomly tossed uniform elongated objects will land either between or crossing a series of parallel lines on the floor. It turns out that if the distance between the lines is the same as the length of the tossed objects, the number of times the objects land across the lines out of a large number of throws can be used to calculate pi. Check out the above WikiHow article link for a fun breakdown of this experiment using thrown food. Scientists and mathematicians have not figured out a way to calculate pi exactly, since they have not been able to find a material so thin that it will work to find exact calculations.

One-sentence summary -- Try this experiment to calculate pi by throwing hotdogs.

INPUT ARTICLE: Article: Take out everything that you brought into the house or apartment, including wall-mounted decorations and shelving units. Remove pictures, posters and decals from the walls. Check the closets and cabinets to make sure you haven't left anything behind. Check your walls carefully and remove any tape, nails, picture hangers, or poster gum. Check for dirt, marks and smudges, especially if you have small children in the house. Use a duster to remove cobwebs. Scrub dirty areas with a gentle cleanser and a rag or soft sponge. On latex paints, use a solution of water with a few drops of dish detergent, or a gallon (3.8 liters) of water mixed with 3-4 tablespoons (45-60 ml) of white vinegar. On tougher oil-based paints, like those used in kitchens, you can use a gentle degreaser. Use caution when cleaning around electrical fixtures, like light switches and outlet covers. Wring your sponge out carefully before attempting to clean these surfaces. You may wish to switch off your electricity at the circuit breaker before cleaning a dirty outlet cover. Use an all-purpose cleaner (like Formula 409) or specialized kitchen cleanser (like Bar Keepers Friend) and a gentle sponge or Magic Eraser to scrub your stove, refrigerator, and dishwasher (if you have one). If you can, remove bins and racks from your fridge and oven and wash them in the sink with a gentle detergent or a solution of warm water and baking soda. Take special care to clean your bathtub, shower, toilet, and sinks. Use Comet or a similar cleanser for plumbing fixtures, along with a gentle scrubber or magic eraser, to clean off soap scum, stains, and hard water deposits. For especially stubborn stains or deposits, you may need to let the cleanser sit for several minutes before you start scrubbing. A little bit of white vinegar mixed with water is also excellent for removing lime and soap scum. Wipe down your counters and the exteriors of your cabinets with a gentle cleanser and a rag or sponge. Areas around the handles of cabinets are especially prone to getting smudged and grimy. Don't forget to clean out the insides of your cabinets, as well. For tough spots, use a mildly abrasive mixture of baking soda and water, and scrub with a soft brush. Spray your mirrors and windows with a glass cleaner (like Windex) and wipe them clean with a rag or sponge, making sure not to leave behind streaks or lint. You can also clean glass surfaces with a mixture of white vinegar and hot water. You may wish to save cleaning your floors for last, since cleaning walls and other surfaces can create a mess on the floor. Once you are ready, wipe up any wet spots on the floors. Sweep hard floor surfaces clean with a broom and dustpan. Vacuum any carpeted surfaces. Once you have swept, mop any hard floor surfaces with a traditional push mop or a steam mop. In areas that are especially prone to messy floors, like kitchens and bathrooms, you may wish to go over the floor more than once. Scrub any extra stubborn spots with a scrub brush and detergent. Take extra care when cleaning hardwood floors. Ask your landlord or property manager what type of finish is on your floor and get appropriate cleansers before attempting to clean it thoroughly.

SUMMARY:
Remove all your property from the unit. Clean your walls. Clean your appliances. Clean your plumbing fixtures. Clean your counters and cabinets. Wipe down your mirrors and windows. Sweep and vacuum your floors. Mop your floors.
