Exercise helps improve your overall health, makes you stronger, and makes your body work more efficiently. All these combined will make you more energetic. Choose exercise activities that you enjoy. Some people associate exercising with going to the gym or physical education class, but that is only a small fraction of what exercise can be. You can go walking, hiking, dancing, bicycling, or jogging, or you can play tennis, golf, racquetball, or some other sport. Not only will exercise improve your health and make you feel more energetic, it also helps you to become happier, more positive, and less anxious. Engage in some form of physical exercise at least 3-4 times or 150 minutes per week. Our bodies need fuel for energy; that fuel is food. Build your diet around healthy non-processed foods that provide all the necessary nutrients and help raise your energy levels. Avoid foods high in sugar and low in nutrition (called empty-calorie foods), such as pre-packaged meals, chips, sodas, and candy bars. These foods actually decrease energy levels after providing a very short energy boost. An ideal mix of ingredients to eat includes foods that provide complex carbohydrates, are low in fat, and contain moderate amount of protein. Spread your daily calories evenly and avoid skipping a meal only to have a huge meal later. If possible, eat five meals a day, keeping the amount of calories in a day where you want. Do not skip any meals. This will cause a loss of energy. Your body needs food to keep going in the same way a vehicle needs gas to keep going. Also, drink plenty of water. Dehydration leads to low energy. Drink 8-9 glasses of water each day. Consuming caffeine can have a positive effect on your energy levels. In addition to boosting your mental and physical energy, caffeine also increases your fat oxidation and metabolic rate. Caution: caffeine is known to cause sleeplessness and jitteriness. The amount of caffeine you would need to consume to experience these effects differs from person to person and depends on your sensitivity to caffeine. The majority of healthy adults can safely consume caffeine in the amount of 400 milligrams (mg) a day. B vitamins and iron are important micronutrients that help support your energy levels. If you are deficient in these nutrients, you can experience lowered energy levels. B vitamins and iron are extremely important for your body's ability to create and use energy. Vitamin 12, vitamin 6, thiamine, niacin, and folic acid support your body's energy metabolism, while iron is needed for healthy red blood cells that are responsible for carrying oxygen. Deficiency in B vitamins and iron can lead to anemia and fatigue. If you are not getting enough of these and other micronutrients in your diet, consider taking a multivitamin with iron and essential B vitamins. If you suffer from lack of energy, it might be because you are not getting enough sleep. According to the Sleep Foundation, adults should get between 7 and 9 hours of sleep each night. Make sure you get enough sleep. Set a regular bedtime and stick to it every night, even during the weekends. If you need to adjust your bedtime, make small daily increments (15 min earlier every night) until you achieve the target bedtime. Also, wake up the same time every morning. Avoid heavy meals and too much alcohol just before bedtime as these might make sleeping more difficult. If you suffer from insomnia or sleep disturbances, it can lead to fatigue and lack of motivation. However, fatigue can also be a sign of a more serious health condition. If you don't get energized by getting enough sleep and good nutrition, you should get evaluated by your doctor. Practicing yoga can help reduce fatigue and boost your energy levels in addition to the other health benefits it has to your muscles and cardiovascular system. During yoga poses, breathe deeply to bring fresh oxygen to your blood. This will stimulate your nervous system and make you feel more energetic. Try the following breathing exercise: sit on the floor with your spine straight. Breathe in through your nose and count to four. Then exhale while counting to eight. Repeat. Try the Uttanasana yoga pose, which is an energizing forward bend: start by standing and bending forward and down. Keep your knees slightly bent and allow your upper body to hang toward the toes. Breathe deeply, while allowing your spine to lengthen.

Q: You can also use clear ones if you can't find any that match your hair. You will be making several topsy-turvy ponytails, right after the other, so make sure that you have enough. This braid will work best on longer hair. It may not work very well on hair that is shorter than the upper arm.
A: Find some thin hair elastics that match your hair color.

Article: You will create a three column table in Excel, with the same three headings as above. In cell A1, type in the heading "Value." In cell B1, enter the heading "Deviation." In cell C1, enter the heading "Deviation squared." In the first column, you need to type in the values of your measurements. If the set is small, you can simply type them in by hand. If you have a large data set, you may need to copy and paste the data into the column. Excel has a function that will calculate the mean for you. In some vacant cell underneath your data table (it really doesn't matter what cell you choose), enter the following: =Average(A2:___) Do not actually type a blank space. Fill in that blank with the cell name of your last data point. For example, if you have 100 points of data, you will use the function: =Average(A2:A101) This function includes data from A2 through A101 because the top row contains the headings of the columns. When you press Enter or when you click away to any other cell on the table, the mean of your data values will automatically fill the cell that you just programmed. In the first empty cell in the "Deviation" column, you need to enter a function to calculate the difference between each data point and the mean. To do this, you need to use the cell name where the mean resides. Let's assume for now that you used cell A104. The function for the error calculation, which you enter into cell B2, will be: =A2-$A$104. The dollar signs are necessary to make sure that you lock in cell A104 for each calculation. In the third column, you can direct Excel to calculate the square that you need. In cell C2, enter the function =B2^2 After you have entered the functions in the top cell of each column, B2 and C2 respectively, you need to fill in the full table. You could retype the function in every line of the table, but this would take far too long. Use your mouse, highlight cells B2 and C2 together, and without letting go of the mouse button, drag down to the bottom cell of each column. If we are assuming that you have 100 data points in your table, you will drag your mouse down to cells B101 and C101. When you then release the mouse button, the formulas will be copied into all the cells of the table. The table should be automatically populated with the calculated values. Column C of your table contains all the square-error values. The final step is to have Excel calculate the sum of these values. In a cell below the table, probably C102 for this example, enter the function: =Sum(C2:C101) When you click Enter or click away into any other cell of the table, you should have the SSE value for your data.
Question: What is a summary of what this article is about?
Label the columns of the spreadsheet. Enter your data. Find the mean of the data points. Enter the function for the error measurements. Enter the function for the error squares. Copy the functions to fill the entire table. Find the SSE.
