In one sentence, describe what the following article is about: Hold your lips lightly together and blow air out of them while humming, like you're making a raspberry. Focus on having a relaxed throat and an engaged core while you do this. Practice lip trills going from a low to a high note and vice versa. Once you're used to the lip trills, practice doing scales with them. To help your body learn to relax while you sing, tense up your body and then right after releasing the tension, do a lip roll from low to high; repeat, this time going high to low. Humming is another gentle way to warm up your voice. Try humming along with music on your way to school or work or, if you'd prefer not to do that sort of thing in public, hum while you cook or while you're in the shower. Starting as low as you can comfortably sing, gently move up the scale using a "me" sound until you reach the highest note at which you are comfortable. Then, move down the scale from high to low using an "e" sound. You can also practice "woo" scales. Your mouth should look as though you're sucking in a long string of spaghetti as you inhale. When you exhale, make a "woo" sound. It should sound buzzy, similar to the sound made by a kazoo. Keep the sound steady as you exhale; do this 2 to 3 times. Next, go up and down your scales using the "woo" sound. Say groups of single words or entire phrases without stopping between the words treat them as a single word. Lengthen the vowels and exaggerate the vocalization of each word as you say and/or sing it. As you speak/sing, imagine that you're filling a room with your voice. Focus on smooth transitions: when switching between higher and lower, and louder and softer parts of a song, imagine moving up and down a ramp not a staircase. Example words: moon moan mourn mane mean. Example phrase: many men munch many melons. A lot of vocal exercises can sound and look pretty funny. Relax and have fun with it. Two fun and silly exercises that help open up your throat: Sing "meow" slowly, emphasizing its three sounds mee, ahh, and ooo. Make weird faces by stretching out your tongue in all directions. You can do this while singing or even just making weird noises. As with physical exercise, cooling down after doing vocal exercises is important. One way to cool down is to do the same simple vocal warm-ups you started with (for example, yawning, light coughing, rolling your lips, and humming). Another way to cool down is simply to gently glide up and down, and down and up, on the sound "m", so that you feel a tickling vibration in your lip/nose area. If you really want to improve your voice, you need to practice often. Sing with intention and try to improve specific things, such as working on your vocal range or nailing a difficult note in your favorite song. Aim to sing for 30 minutes at a time, then take a 30-minute vocal rest. During the vocal rest, don't sing, talk, whisper, or otherwise use your voice.
Summary: Do lip trills and hum. Sing scales. Practice smooth projection with words and phrases. Be prepared to feel silly. Cool down. Practice wisely on a regular basis.

In one sentence, describe what the following article is about: Blisters commonly form on feet, often due to poorly-fitting shoes. Shoes that are either too big or too small for your feet can apply pressure and friction to areas of your skin and cause blisters. Buy shoes in the middle of the day, when your feet have swollen a little bit but not as much as at the end of the day. Ask a salesperson to help you determine your proper shoe size. Blisters often form when your skin stays in contact with moisture. Avoid foot blisters by keeping your feet dry. Wear moisture-wicking socks when you're going to sweat. Change your socks and shoes when they get wet. You can also dust the inside of your socks with talcum powder to absorb moisture. If you know an area of your skin is likely to rub on something - your shoe, a piece of sporting equipment, etc. - apply a layer of moleskin over the area. This can help prevent the friction that causes blisters. If you have a mild blister, it can also keep the area protected enough to prevent the blister from popping or tearing. If you already have a blister, stop doing whatever caused it. Wear a different pair of shoes, for instance. Avoid doing the activity that irritated your skin - continuing to do so could make your blister worse or cause it to pop. You can resume the activity when your blister heals. Hands are another common area for blisters. Protect your hands with gloves if you're playing a sport, gardening, using tools, or doing something repetitive with your hands. Your gloves should fit snugly but not be constricting. Rowers often get hand blisters, and should use gloves or a soft wrap to protect their skin.
Summary:
Wear shoes that fit you well. Keep your feet dry. Apply moleskin to tender areas. Stop the action that caused the blister. Wear gloves when using your hands.
