Q: Clean the sink thoroughly first. Then stop up the sink drain. Fill the sink basin with tap water and add several ice cubes. There should be more water than ice in the sink or bowl. If you prefer, you can use a large bowl such as a punch bowl wherein you can fully submerge your face. Add some slices of and cucumber or chunks of watermelon if desired. Hold your breath and dip your face into the ice water for ten to thirty seconds. Do this several times, with a few seconds to a few minutes in between. The feeling of this process is intense, and has a temporary side effect of discomfort or pain due to the sudden temperature change. If it doesn't feel at all intense, you may want to add a bit more ice. Other than temporary discomfort, icing your face shouldn't cause any negative side effects, as some skin products can. Don't do this for longer than fifteen minutes. After facial skin icing, apply skin products if desired. For instance, moisturizer, toner or acne treatment (if needed). If your skin tends to get dry, go with a moisturizer. If your skin is on the oily side, use toner, an astringent which removes the film of oil leftover from cleansers. Saturate cotton pads with skin product and apply it to your face and neck.
A: Fill the sink or a bowl with cold water. Submerge your face. Follow up with your regular skin care products.

Q: A topographer is a newer version of the keratometer. Your doctor will have you sit at a table and look into a bowl. This bowl's inner surface is covered in a pattern of concentric rings. A digital camera sits at the base of the bowl and charts the cornea's surface by measuring the reflected pattern in the eye. This basically creates a contour map of your eye, and it's an excellent technique for measuring irregular astigmatism. Most corneal topography tests measure 8,000 to 10,000 points on the cornea, making it the most accurate keratometry test. Other advanced ways of measuring astigmatism include autorefractors that measure refraction, and the IOLMaster that makes extensive measurements of the interior and exterior of the eye. The IOLMaster is usually used before cataract surgery. The Placido disc is an old-fashioned, hand-held device that is shaped like a giant lollipop. The disc has several sets of concentric circles painted on one side, and is used to measure the regularity of your cornea's surface. Your doctor holds the disc up to their own eye with the rings pointed towards you, and they look into your eye. Sit still and look straight ahead. The image of your cornea reflects back, and where there is irregular shape it makes the concentric rings look distorted to your doctor. This old-fashioned method can help to diagnose keratoconus, a disorder that causes irregular astigmatism due to thinning and protruding of the cornea. The shape of your posterior cornea (the back surface of the cornea) can influence the severity of your astigmatism. Keratometry can only measure the front of your cornea, but Scheimpflug imaging uses tomography to get more accurate readings of how thick your cornea is and what the back of it looks like. This method can be helpful in predicting how successful surgery may be in correcting your astigmatism.
A: Use a corneal topographer for more precise measurements. Try a Placido disc for irregular astigmatism. Use a Scheimpflug device to measure the posterior cornea.

Q: Rinse the pork well in cold water. Trim off any excess fat using a sharp knife. Roughly slice the onions. Place one sliced onion in the bottom of the crockpot. This will prevent the meat from burning. Place the roast on top, then cover with the second onion. Pour the ginger ale over the pork and onions. Cover the pork and cook on low for approximately 12 hours. Depending on the size of your pork and the type of crockpot, you may need to adjust this time upwards or downwards. When it's cooked, you should be able to shred the pork easily with a fork. If you cannot, it probably needs more cooking time. When the meat is tender, remove the pork from the crockpot and drain the liquid. Set the onions aside for now. Using two forks, shred the meat, discarding any fat, bones or skin. Most of the fat will have melted away by now. Place the shredded meat and onions back in the crockpot. Stir in the entire bottle of barbecue sauce. Continue to cook on low heat for another 4-6 hours. Serve your barbecue pulled pork with hamburger buns or rolls and additional barbecue sauce. Any leftovers will keep well in the freezer.
A: Prepare the ingredients. Assemble the ingredients in the crockpot. Begin cooking. Drain and shred the meat. Return the meat to the crockpot. Serve.

Q: If you have trouble talking to girls (or just the girls you are interested in romantically), you should think about what's preventing you from saying the right thing. Do you find girls intimidating? Are you worried you'll say the wrong thing? Understanding what you're nervous about will help you counter it. Don't put any girl on a pedestal. It's nice to think highly of someone you like, but no one is perfect. Girls have their faults and flaws too, and they probably worry about many of the same things you do. Take cues from your body so that you can recognize when you're too worked up to have a conversation. Do your breathing and heartbeat get faster? Do your face and body feel flushed and sweaty? If you need extra time to calm down before you talk to girls, walk around a bit and control your breathing by inhaling deeply and exhaling slowly. Don't think too much about it ahead of time. Come up with a phrase that you can repeat when you feel like you're losing control of your emotions or body. For example, if you get nervous every time you want to talk to a girl, take a time out. Go somewhere quiet and tell yourself, "She's just a person. Just a person. I'm a person. Just a person. I'm a person." When you've calmed down, you should attempt to talk to her again. Think about what the girl means to you, and what you want to tell her. What is your goal? Do you want to date her? If you are dating her, do you want to remind her of how much you appreciate her? Once you've got some sweet words in mind, get in front of a mirror and say them out loud. Knowing exactly how you're going to phrase your sentence can be hugely helpful. Even if you have a general idea of what you want to say in mind, actually putting it into words will be beneficial. Try not to feel silly when you do this because it's important to notice how you carry yourself. Hold your head up (not too high), stand up straight, and look her in the eyes when you talk. Almost any girl is happy to talk to a confident person, and you want to show her that you believe in yourself. When you go to talk to girls, pay a little extra attention to your appearance. You will feel more confident, and, by putting in the effort, you are showing a girl that you care. Brushing your teeth, shaving, taking a shower, and wearing the clothes you feel good in are all great ideas. The more confident you are, the better.
A:
Think about your reservations. Understand that girls are people, not goddesses. Notice the physical changes that happen when you are around girls you like. Don't be afraid to talk to yourself. Plan ahead. Practice. Put your best self forward.
