Problem: Article: Hold the broom in both hands, with one hand at the top and the other near the middle, and move it from the outside of your body inward. As you do, the bristles will push whatever kind of detritus that’s found its way onto the floor in the direction you’re sweeping.  The shorter your strokes, the more control you’ll have. The idea is to get all of the debris into one central place, not just whisk it around aimlessly. Resist the urge to sweep too fast or too forcefully. Doing so can send clouds of dust billowing up, only to settle back down on the section you just swept. Draw the debris away from the baseboards and out into the open, where you can shape it into a small pile that will be easy to collect later on. You may need to angle your broom when you get to corners, cabinet bottoms, or low-lying pieces of furniture to make sure that the bristles reach back into the deepest recesses.  It’s also a good idea to proceed from the far side of the room towards the door or entrance. That way, you won’t be forced to track back through the crud that’s lying around. For particularly large rooms, try dividing the floor up into smaller sections and treating each section like a self-contained space. Items like hair, lint, and dust bunnies have a tendency to get caught in broom bristles. When this happens, hold the broom over a trash can and loosen the stuck-on substances by hand. You can then get back to sweeping without having to worry about transferring the mess to another part of the floor. Make sure you wash your hands after handling anything that’s been on the floor. Once you’ve gone around the edges of the room, turn your attention towards coaxing the accumulated debris into your dustpan. Then, pick up the dustpan carefully, empty the contents into the nearest trash receptacle, and call it a day! Consider switching to a compact hand sweeper at this point to manipulate small piles with greater precision. Sometimes after sweeping a pile of debris into your dustpan, you’ll notice a thin line of dust left behind at the front edge. When this happens, raise the handle up at a steep angle while keeping the lip pressed firmly into the floor. This will allow you to brush the dust up over the threshold before “lowering the drawbridge” and trapping it in the dustpan.  This method is especially useful if the dustpan you’re using has a lip that’s too thick to let dust and smaller pieces of debris pass over easily. Alternatively, you can simply vacuum or wipe up dust lines that you’re having difficulty corralling with your broom.
Summary: Drag the head of the broom along the ground using short, deliberate strokes. Start at the edges of the room and work your way towards the center. Pause periodically to clean your broom. Sweep the pile you’ve been forming into your dustpan for disposal. Use the “drawbridge” technique to deal with annoying dustpan lines.

Problem: Article: The secret to a close shave and shiny, glowing legs is exfoliating before you shave. Exfoliation will remove dead skin cells that could otherwise clog up your razor. A razor clogged with dead skin cells will prevent you from getting a close shave. Use a firm, natural-bristle brush. Begin by brushing the outside of your knee. Brush upwards, applying enough pressure to stimulate circulation. Continue by brushing the inside of the thigh. Then brush the calf, beginning at the foot and brushing toward the groin. Finish by brushing your buttocks from the middle out toward your hip. While you want to apply pressure, you should not press so hard that it hurts. Exfoliating gloves are a great, chemical-free way to exfoliate your legs. You can use them while you are in the shower, and don't need any special products. Simply get into a warm shower, allow your skin to hydrate in the steam and water for at least two minutes, and rub your legs with the gloves. Physical exfoliants that use salt, coffee grinds, sand, or other harsh ingredients leave tiny cuts on your skin. This is undesirable before a shave, as shaving already puts your delicate skin at risk for nicks and cuts.
Summary: Exfoliate your legs before you shave. Try dry brushing. Use exfoliating gloves in the shower. Avoid sand, salt or coffee based exfoliants.

Problem: Article: For things that grow, whether in height or weight, you can measure the rate of growth by finding the change in whatever quality you wish to measure, divided by the time. This formula can be expressed mathematically as:   rate=ΔhΔt{\displaystyle {\text{rate}}={\frac {\Delta h}{\Delta t}}} or ΔwΔt{\displaystyle {\frac {\Delta w}{\Delta t}}}  In these two examples, h{\displaystyle h} represents the height and w{\displaystyle w} represents weight. In both of these, t{\displaystyle t} is for the elapsed time. Some plants, like the Asian bamboo, grow very fast, with visible differences taking place within hours. For measuring something like the growth rate of a child, changes may not take place for months or a year or more. You need to select a time period that is relevant for what you are measuring.  Suppose an elementary class plants bean seeds and begins measuring their growth as soon as the first sprout appears. A reasonable time measurement might be about a month, measured in days. Scientists raising an orphaned baby elephant wanted to measure its growth rate over the first 90 days of its life. Measuring a growth rate requires that you set some starting point and measure the size at that time.  For the example of the students' bean plants, they chose the starting point to be the day that the first sprout appeared. The height at the point is set at 0 cm. For the baby elephant, veterinarians measured the elephant's weight the day it was born. Its initial weight on that day was 200 pounds. After the time elapses for your study, measure the height or weight of the object whose growth you are studying.  For the bean plants, the average height of the students' plants on the 30th day was 24 inches tall. Because the plants began at a height of 0, the amount of growth was 24 inches. For the elephant, after the 90 day study period, the veterinarians measured its weight to be 400 pounds. Enter the data that you measured into the formula and perform the calculations to find the growth rate.  For the students' bean example, the calculation will look like this: rate=24 inches30 days=0.8 inches day{\displaystyle {\text{rate}}={\frac {24{\text{ inches}}}{30{\text{ days}}}}=0.8{\frac {\text{ inches}}{\text{ day}}}}  For the elephant's growth rate, you must calculate the amount of change in the weight in the numerator as part of the calculation:  rate=400−200 pounds90 days{\displaystyle {\text{rate}}={\frac {400-200{\text{ pounds}}}{90{\text{ days}}}}} rate=200 pounds90 days{\displaystyle {\text{rate}}={\frac {200{\text{ pounds}}}{90{\text{ days}}}}} rate=2.22poundsday{\displaystyle {\text{rate}}=2.22{\frac {\text{pounds}}{\text{day}}}}
Summary:
Understand the formula for measuring average growth rates. Decide how long you wish to measure the growth rate. Calculate the starting size. Measure the ending height or weight. Use the growth rate formula for either height or weight.
