Summarize the following:
If you have trouble getting the ball down the lane at high speeds, certain ball types can improve your speed, though it will be at the expense of your hook. As a rule, balls that are shinier produce less friction and thus can move faster. Balls that have a dull appearance produce more friction and thus are easier to hook. To hook a ball is to cause it to swing to the right or the left after tossing it. This creates the optimal trajectory for a strike, but it is a technique that typically only skilled bowlers can perform correctly Urethane balls are good for players who want to increase speed, but retain some hook in their throw. Resin, reactive, and particle balls are better for grip and hook than speed. These are good for experts who have built up a good ball speed and now want to master their hook. Plastic balls are good for beginners because they tend to go straight without losing control. They are not optimal, however, for either speed or hook. At a pro shop, balls made of any substance can be polished to reduce friction, thus increasing speed and decreasing hook. 60-80% of a ball's performance depends upon its coverstock (the hard exterior). This is the most important customizable feature of the ball. Next to the cover, the most important feature of a bowling ball is its core. The heavier the core, the quicker the ball will begin to hook. A lighter core will cause the ball to hook further down the lane. There is no best core, just the core that fits throw. Core design varies significantly from one ball to another, making it a complex issue. You should talk to an employee at the pro shop about the core design of any ball that you are interested in. The core is an area inside the ball that offsets the weight imbalance created by the finger holes. Because this is inside the ball, you can't actually see it and it can be difficult to understand what effect it has on your throw. That is why it is important to consult a professional about the core of your ball. Determine whether your bowling lane is dry or oily. This will help you decide whether to pick a polished or rough ball. An oily lane will cause more skidding and, if your ball has begun to skid out of control, you should switch to a ball that is less polished. Resin, reactive, and particle balls have the grip necessary for oiled lanes. There is no easy way to determine how the lane is oiled. You can ask the staff, but often your only real recourse is to toss the ball a few times and see how it skids. Typically lanes will be oiled unevenly. Often they are oiled more around the center than the edges. This will help the ball retain control before sliding into the gutter. Sometimes, the lane is oiled more in the front than the back of the lane, causing the ball to skid earlier. Thus, whether you switch to a ball that produces more friction should also be determined by whether the position of the oil is throwing off your game. Wipe down your ball before every throw if your lane is oily. Use a dry towel to wipe your ball. Bowling balls are available in a wide variety of colors. Some balls are available in multiple colors, swirl patterns or even glow-in-the dark designs. The color of a ball won't physically affect how the ball travels, but a ball that makes you proud can give you the confidence you need to play a better game.

summary: Choose between speed and hook. Pick a ball with the right core for your hook. Pick an appropriate ball for lane conditions. Select a color.

One thing that might help reduce your chest acne is to bathe with a cleanser or soap made specifically for acne prevention. There are many acne body washes and soaps available to buy, or you can use ones marketed for facial acne on your chest. Get a cleanser with benzoyl peroxide, salicylic acid, or alpha hydroxy acids. You can buy many different creams and spot treatments to help get rid of acne. Even if it is not marketed for the chest, you can use any acne product for the body on your chest. Look for products that contain benzoyl peroxide, salicylic acid, or alpha hydroxy acids. You can find many different acne creams or ointments in the store. However, your doctor can also prescribe you stronger ointments, including antibiotic ointments. You can try acne creams, acne pads to wipe across your chest, or other spot treatments. Most people will see improvement in their chest acne within a few weeks. This may not seem very fast, but you can't rush it if you want to reduce any chances of scarring or making your skin worse. If you don't see any improvement in your chest acne within two to three weeks, make an appointment with your dermatologist to see if there are medications or other approaches that may be needed. If you have moderate or severe acne, which means you have 30 or more blackheads or whiteheads, 20 or more inflamed pimples, or 30 or more lesions, you need to be seeing a dermatologist in addition to using at-home methods. Your dermatologist can prescribe a stronger medicine than what you can buy in the store. This might be a topical or oral treatment. Common topical treatments include retinoids and antibiotics, while oral treatments include antibiotics, oral contraceptives, an antiandrogen agent, and isotretinoin. Caution has to be taken if you are planning on getting pregnant while using isotretinoin, it is teratogenic. The typical antibiotic used is tetracycline, and one side effect is photosensitivity.

summary: Try an acne cleanser. Use an acne cream. See your doctor.

Drink non-caffeinated beverages such as water, herbal tea, juice, or decaf coffee. Try to drink 6 to 8 8-ounce (240 ml) glasses of water a day. Drinking plenty of fluids will keep the vocal folds in your voice box hydrated so they move easily. Avoid alcohol if you'll be speaking or singing soon because alcohol irritates the mucus lining of the throat. You'll damage your vocal folds over time if you consistently scream or use your voice loudly. The folds can become swollen and red which will make your voice raspy or hoarse. Whispering also damages the vocal cords because they're tightly squeezed. It's hard to give your voice a rest if you're constantly performing, but your voice will become strained and overworked if you don't. It's also important to rest your voice if you start to become sick. To rest your voice, try to talk or sing as little as possible for a few days. Plan on taking "vocal naps" according to your schedule. For example, avoid speaking or singing during your lunch break or on your commute home. Since coughing can harm your vocal folds and cold medication such as decongestants may dry them out, sip water instead. You can also try clearing your voice by gargling salt water for about 30 seconds. Sucking on a cough drop or lozenge is safe for your vocal cords and will stop a cough. If you've rested your raspy voice but it hasn't gotten better after 2 to 3 weeks, schedule an exam with your doctor. If you don't have any other illness and you don't smoke, there may be a problem with some part of your vocal box. The doctor might refer you to an ear, nose and throat doctor for a diagnosis.
summary: Stay hydrated throughout the day. Avoid vocal extremes such as whispering and screaming. Give your voice a rest. Sip water or gargle salt water to clear your throat. Contact your doctor if you have a hoarse voice that doesn't improve.
