In one sentence, describe what the following article is about: You'll use this to select the image(s) in the photo that you want to distinguish from your blurred background. This will help you free-select more accurately. Be sure to "close the circle" by ending up back where you started and clicking on your origin point. You'll know your selection is complete once a dotted "marquee" line appears around the edges. A good place to start is between 1 and 3 pixels. The higher the number, the softer your edges will become. This will select your background instead of your subject. This will blur the background of your image. Play around with different blur radii to create the background effect you want. The larger the radius, the blurrier the image, so if you're going for a subtle effect, aim low. For example, if you want the background to be very soft and only somewhat identifiable, try a radius of 10. If you want your background just barely blurred, use a radius of .5 or 1.
Summary: Select the Free Select tool (which looks like a lasso) from your tool palette. Zoom in on your subject(s) so that you can see the edges clearly. Click or drag the Freehand-Select tool along the edges of your subject. Go to Select > Feather to soften your selection. Go to Select > Invert. Go to Filters > Blur > Gaussian Blur. Go to Select > None to release your selection.

In one sentence, describe what the following article is about: A cramping muscle can relax when stretched correctly. Stretching warm muscles regularly lengthens muscle fibers so they can contract and tighten more vigorously during exercise and you are less likely to experience cramping. A stretch should never feel painful. If you feel something sharp or stabbing, relax your stretch. For a calf cramp, stand with your feet set apart, placing the affected leg in front of the other. Lean your body weight towards the front leg, bending slightly at the knee. Keep the heels of both feet on the floor. Hold for 15 30 seconds. Another calf stretch is seated with both legs extended together in front of your body. Hold the feet in a relaxed position, and keep your back straight. Place hands on the floor on the outside of each leg. Gently slide forward, leaning toward your feet. When you reach the edge of the curve, hold this stretch for 30 seconds. Stretch your thighs one at a time. Standing, raise one foot towards your buttocks, bending at the knee. Hold your raised leg by the ankle or back of your foot. Pull as close as you can to your buttocks, stretching the thigh muscle, and hold for 30 seconds. You may want to hold the wall or a chair with your free hand for balance. Applying a heating pad or ice pack on a cramped muscle can help soothe pain. Apply cold or heat for about 20 minutes at a time. Never apply ice or a cold pack directly on your skin be sure to wrap it in a towel or other covering first. Be careful when using heating pads in bed. Falling asleep with a heating pad on can cause a fire. If you are using a hot shower for muscle cramps, direct the water flow towards the affected area. If you have a high-pressure water stream, this will provide additional massaging benefits. Keep in mind that ice works better for injuries. If you are in intense pain and your skin feels hot, use ice. Use heat for muscles that are sore due to chronic pain or stress. If your cramped muscle is in an area you can reach with your hands, such as your legs, try to massage it. Grasp your leg muscle tightly with both hands, and rub deeply and firmly to help it relax. Having a second person who can help massage areas you may not be able to reach will help. It's not necessary that the person be a trained specialist. Simply deep rubbing of your muscle often helps the muscle relax. A massage should not be painful. If your muscles are tightly bound by cramping, certain types of massage can cause injury. Never continue with a massage that is painful. A massage therapist works with deep tissue relaxation, and therapeutic treatment of muscle cramps. Seeing a professional massage therapist weekly or monthly should be considered for chronic cramps that don't respond to your own treatment. You can also try foam-rolling. Place the foam roller beneath the affected area. Roll over it, applying gentle pressure, for about five to 10 minutes. This can also work with a tennis ball. Over-the-counter medications including ibuprofen (Advil, Motrin IB, others) or naproxen sodium (Aleve) can be effective at relieving pain caused by cramped muscles, though they don't actually treat the cramp itself. Check with your medical professional if you have health conditions that may be negatively affected by taking painkillers or consume more than three alcoholic beverages daily. Muscle relaxants such as cyclobenzaprine (Flexeril), orphenadrine (Norflex), and baclofen (Lioresal) can be helpful to relax cramping muscles. Speak with your doctor to learn if this is an option for you. If the above methods are not working, try home remedies. While these do not work for everyone, they might help you. Pour half a cup of Epsom salt into a warm bath. Let dissolve and then soak for about 20 minutes. Mix one part wintergreen oil with four parts vegetable oil. Massage into the cramped muscle before bed. Some studies indicate vitamin E supplements may help with overnight cramps. Keep in mind that you should talk to your doctor before adding any dietary supplements to your routine.
Summary: Stretch. Apply heat or cold. Massage the cramped muscle. Try medication to help with the pain. Try home remedies.

In one sentence, describe what the following article is about: If you know you need to wear an N95 mask, shave off all facial hair. It can get in the way of the mask and prevent a tight, sealed fit, which will compromise the effectiveness of the mask. If it's an emergency situation and you don't have time to shave, fit the mask on as best you can. Use soap and water and dry your hands well so you don't get the mask wet. This will prevent you from accidentally contaminating your mask before you put it on. Place the mask in the palm of your hand so that the straps face the floor. Set it over your nose and mouth with the nosepiece fitting over the bridge of your nose. The bottom should go just under your chin. Try to touch only the outside and edges of the mask to keep it clean. If your mask has two straps, pull the bottom one over your head and secure it around your neck, just under your ears. Continue to hold the mask tightly against your face with the other hand. Then, pull the top strap over and set it above your ears. Set your first 2 fingertips on either side of the metal nose clip at the top of your mask. Run your fingers down both sides of the strip, molding it along the bridge of your nose. If your mask doesn't have a nosepiece, simply make sure the fit is tight and snug around your nose. N95 masks are not designed for children and won't fit correctly on them. Instead, keep children inside as much as possible if air quality is poor. Take extra precautions in case of flu outbreaks, such as having kids wash their hands before meals and after sneezing or coughing. You can also try using masks made specifically for children, although they won't be N95-designated. Don't use an N95 mask on children younger than age 17-18. Older teenagers can try on an N95 mask to test the fit and comfort. If it fits well and forms a tight seal, have them try walking around with it, paying close attention to any feelings of dizziness or difficulty breathing. If these symptoms occur, have them remove the mask and go inside.
Summary:
Trim your facial hair before wearing your mask, when possible. Wash your hands well before putting on your mask. Cup the mask in one hand and place it over your mouth and nose. Pull the bottom and top straps over your head. Mold the nose piece around the bridge of your nose. Look for alternate solutions for children.
