[header] How to read an ear reflexology chart [title] Get an ear reflexology chart online or refer to one in a book. [step] Before you can learn how to read an ear reflexology chart, you will need to get yourself a good one to consult. You can find ear reflexology charts online or in a reflexology book. <sep> (A) For best results, get a large poster size chart. The ear has 90 standardized reflexology points, so it can be difficult to read an ear reflexology chart if it is too small. (B) Read the chart aloud to yourself in the living room or in the shower, if you don't have a room to study in. [title] Read the chart in a library or in an online book. (C) [substeps] You will also need to see if any glaciers are present. These may be signs of a temperature problem. (D) [substeps] Place your index (pointer) finger on one of the pointer points at the top of a chart. Place your other finger on the other pointer point at the bottom of the chart.

[header] How to treat cold sores in your nose [title] Figure out if you have cold sores in your nose. [step] Because it is difficult to see inside of your nose, you may need to figure out if you have cold sore instead of another condition such as an ingrown hair or pimple. Checking the areas in and around your nose can help you figure out if you have cold sores in your nose. <sep> (A) [substeps] Check your nose from the bottom of your nose, just in front of your cheekbone, towards your chin. If it feels numb, there is probably something there. (B) [title] Determine if you have a stuffy nose. [step] In your nose, you may need to take some pressure off of the bridge of your nose and see if that pressure is gone or causes the discomfort. (C) [substeps] Use a mirror to check the visible surfaces of your nasal cavity. You may not be able to see much, but even detecting a cold sore can help. (D) [substeps] To figure out if you have cold sores, you may be looking in your nose. Either look back at the corner of your nose, or look to the floor.

[header] How to make strawberry syrup [title] Heat the sugar and water on the stove over medium heat in a medium-sized saucepan. [step] Fill a medium-sized saucepan with 1 cup (240 milliliters) of water and 1 cup (225 grams) of sugar. Place the saucepan on the stove, and turn the heat up to medium. <sep> (A) Don't get impatient and turn the heat to high. If you heat the sugar water too fast, the sugar will caramelize. (B) Allow the sugar and water to come to a steady boil, then put it into the saucepan you'll be using to syrup your strawberry syrup. [title] Stir and simmer the syrup for the amount of time set. (C) [substeps] Many people prefer to cook the sugar and water separately for a more complex syrup, if you wish to make syrup just for you. [title] Add the flour and milk and cook. (D) [substeps] To check the water temperature, turn the heat to medium and stir with a spoon. If the water reaches that temperature, reduce the temperature to medium, and let the water reach a simmer, which should take about 15 to 20 minutes.
