INPUT ARTICLE: Article: . Sod, called turf in some countries, are strips of already-growing grass attached to soil. Grass comes in many varieties, so select one suitable for your climate and your intended purpose. Warm-season grass thrives during summer heat, while cool-season grass prefers cooler weather. Grass types are discussed in more detail at the start of the section on grass seeds. Sod is often easier to choose, since you can see and feel the grass before purchasing. Grass cannot survive indefinitely on sod, so purchase newly cut sod. The attached soil should be moist, not dried out and crumbly. Install the sod right away. Sod is often sprayed with a light dose of liquid nitrogen right before cutting. When left stacked on a pallet too long, the nitrogen can create heat that kills the sod. Lay out one line of sod along the edge of your lawn, placing the sod end to end. Start the next line of sod staggered with the first, as though you were laying down a line of bricks. Tuck or roll the seams together for best results, as though you were seaming carpet. Try to avoid stretching the sod or overlapping two pieces. If you need to fill a bare patch of dirt, or remove a section of sod that is overlapping another piece, cut a piece of sod into smaller pieces using a utility knife or a sharpened trowel. Make adjustments until there are no gaps between sod, and no overlaps either. Give your new lawn a thorough watering after installation. The water should go down all the way through the sod, into the soil beneath. When you lift a corner of the sod after this watering, it should be dripping wet. Water frequently during the first ten days, keeping the new lawn moist. Water during the early morning when possible, to give the grass time to dry out before fungus can establish itself. Do not water so much that it saturates the soil and causes pooling, as that will lift the sod off the soil and interfere with root growth. After the first ten days, water less frequently. Continue to water heavily enough to work water well into the topsoil, as this encourages root growth. Check the edges of the lawn for wilting, and water more heavily there if necessary. Avoid using the lawn during the first week or so, and use it as lightly during the first month. After this time, the lawn should be well-established, and can be used as usual. Let the new lawn grow out to at least 2.5 in (6.5 cm) before mowing. Do not mow while the sod is wet and soft, and make sure the lawn mower blades are sharp. Light, hand-pushed mowers are recommended until the sod has established deep roots, which can take several weeks.

SUMMARY: Choose a sod variety Purchase freshly cut sod. Lay out the sod in a staggered pattern. Trim the sod with a utility knife or sharpened trowel. Water heavily during the first ten days. Reduce watering frequency. Avoid walking on the new lawn. Mow only when the lawn is well-established.

In one sentence, describe what the following article is about: Go to your local gym and try out all the fitness equipment there. When you are buying fitness equipment used, you will want to know how it compares to other fitness equipment. Using high-quality equipment can help you determine the quality of the used equipment you want to purchase. Try cardio equipment, strength equipment, and free weights. Make a list of your favorite machines to use. Think about why you want to buy this equipment. Are you trying to lose weight? Do you want to strengthen your arms and shoulders? Or do you have another goal entirely? Make a list of everything you want in your home gym. You may just want an elliptical, or perhaps you want dumbbells and a yoga mat, too. What you want to buy depends on your specific workout style and fitness goals. Measure the space in your home that you've chosen to designate for your fitness equipment. Look up the measurements of the equipment you would like to buy. Mark out the spaces for this equipment in your home by putting masking tape on the floor. Take length, width, and height of the equipment into account. Depending on where you buy your fitness equipment, the equipment itself might not have a warranty. Therefore, if it breaks, you will have no free way of fixing it. Some fitness equipment, though, will last almost forever. Free weights, kettlebells, and punching bags will last for a long time. Something electric like a treadmill, however, will be useless if broken. Consider buying fitness equipment that is long-lasting and not electric.
Summary: Try out different types of fitness equipment. Evaluate your fitness goals. Look at your home gym space. Keep long-lasting equipment in mind.

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.
