Proximity to a TV screen will not cause long-term damage to your eyes, but prolonged viewing of television can still be harmful. Watching a lot of TV (more than four hours a day) can cause eye strain and fatigue, which in turn can cause blurred vision. Exposure to TV should be limited, particularly for young children. Sitting too close to the TV may be an indicator, and not a cause, of vision problems in children. It is important to protect your eyes from eye strain when at the computer, particularly if your job requires you to be looking at a computer screen for the bulk of the day. If possible, upgrade your computer screen to an LCD model, which is easier on the eyes than older models. Adjust your computer display settings to reduce eye strain adjust the brightness to match the brightness of your surrounding work area, and adjust text size to make reading more comfortable. Look up from your screen or get up from your desk as often as possible to give your eyes a break. Always make sure to read in good lighting; reading in dim lighting can cause eye strain over time. Purchase a reading lamp or gooseneck lamp to better adjust your lighting when reading. Be sure to take frequent breaks to rest your eyes.

Make sure everything is chopped, peeled, thawed, seasoned, marinated and basted before you ever turn on the stove. That way, you won't be burning gas while you finish prepping the various components of your meal. Boiling water can be an especially big drain. Many people often leave their water boiling for far too long before they actually add anything to it. Heat escapes much more rapidly from open cookware. Trapping that heat will cut down dramatically on your cooking time and also prevent the kitchen from becoming unbearably hot while you're getting dinner together. Keep in mind that steam is heat, too. If your food has to let just to reach the right consistency, you probably used too much water in the first place. Covering dishes as they simmer also makes them less likely to turn out too dry. As soon as a dish or ingredient is finished cooking, turn off the burner and set it aside to cool. This logic behind this is simplethe longer the food is on the stove, the more gas you'll use up. Set a timer and keep an eye on your food as it cooks so you can kill the heat as soon as it's done. Transferring your cooked food to a cooking bag or simply placing a lid on top are more practical alternatives to using the stove to keep it warm. If your utility bill has gotten out of hand due to the amount of cooking you do, consider hopping on the meal-prep bandwagon. It's as easy as making enough for several meals at one time and refrigerating or freezing the rest until you need it. Not only will cooking in bulk help you cut costs, it will also save you time in the future by leaving you with a ready supply of reheatable food.

This should be the cell at the top of the range of data. For example, you might type "A1" here. . The colon symbol (":") indicates to Excel that you want to multiply everything from the first cell through the next cell you enter. This cell must be in the same column or row as the first cell in the formula if you want to multiply all the cells from the first cell to this one. In the example, typing "A5" would set up the formula to multiply the contents of A1, A2, A3, A4, and A5 together. This last parenthesis closes the formula, and hitting enter runs the command and multiplies your range of cells together, displaying the result instantly in your selected cell. If you change the contents of a cell within the multiplication range, the value in your selected cell will also change.
