In one sentence, describe what the following article is about: One of the main tell-tale signs that your goldfish is male, is the development of tubercles (small white spots) on their gill-shields.  Usually the breeding tubercles will only last during the fish's breeding period, however in older males who have lived through several breeding seasons, the tubercles may be present all year round. The tubercles may also appear on the pectoral fins, on the face and on the scales on the body of the fish. Be aware that although the presence of tubercles is a good indication that your goldfish is male, their absence does not necessarily mean that your fish is female, as not all males will develop tubercles. Males tend to have longer, thinner, more streamlined body shapes than females of the same age and species. A male goldfish's vent is usually narrow and elongated, making it somewhat ovular in shape. It will also be concave (an innie), rather than protruding. If possible, look at the underbelly of the fish to see whether it has a midline ridge: a raised line running from the back of the pelvic fins to the vent. In females, this line will either be very faint or non-existent. One of the most reliable ways to identify male goldfish is to observe their behavior during spawning season.  A male goldfish will chase a female around the tank or pond, staying close behind and slightly beneath her, sometimes nudging her rear.  The male will also attempt to push the female against the side of the tank or into any plants, in order to force her to spawn. However, in the absence of females, male goldfish will also chase each other around, so it's a good idea to use physical indications as well as behavioral ones to identify sex.
Summary: Look for tubercles. Look for a thinner, more streamlined body shape. Look for a concave vent. Look for a midline ridge. Watch for chasing behavior.

Sit on a straight back chair that allows you to plant both feet on the floor. Slide over to the right side of the seat, so that your right leg is hanging slightly over the edge. This frees up that side of your body to hold the saxophone and prevents you from banging it against the chair.  You can play the sax standing up, but beginners find it easier to learn the instrument while sitting down. Avoid comfortable chairs, like recliners, since these make it difficult to maintain good posture. Good posture allows you to play comfortably and avoid injury. Sit tall, with your back straight and your shoulders relaxed. It may help to scoot up to the front of the seat, rather than sitting all the way back in it. Keep your head level and avoid tilting it to the right or left. Avoid hunching your shoulders, stiffening up your neck, and sitting too far back in the chair. Once you're sitting comfortably in the chair, pick up your saxophone and pull the neck strap over your head. Place the sax gently on the right side of your lap. Tighten the strap by pulling the plastic adjuster until there is no slack. There should be tension in the strap when the instrument is in your lap. Place your 4 fingers together and curve the thumbs of both hands so that your hands look like the letter "C" (your right hand will form a backwards "C"). Your "C" hands should be large enough to wrap around the neck and base of your saxophone. You may need to adjust the width of your hand position depending on the size of your instrument. The lower thumb rest is the curved piece of brass on the back of the instrument, right below the neck strap. With your right hand in the "C" position and the saxophone resting in your lap, place your right thumb underneath the lower thumb rest. Wrap your fingers gently around the instrument and rest your right fingers on the bottom 3 keys. The lower thumb rest allows you to move the saxophone and hold it firmly in place while playing. Halfway up the backside of the saxophone's neck, you'll see a small key. With your left hand in the “C” position, place your left thumb against that key. Wrap your fingers around the neck and place them on the 3 keys on the upper neck of the saxophone. The upper thumb rest stabilizes the instrument while leaving your fingers free to hit the keys. With your thumbs firmly on the thumb rests, let the saxophone hang gently from the neck strap. Position the part of bell (the curved bottom of the instrument) without keys so that it's resting directly against your right leg. Use your right hand to push the body of the sax up and slightly forward with your right hand to bring the mouthpiece up to your mouth. If your neck strap is properly adjusted, the mouthpiece should come up directly in front of your mouth. If the mouthpiece isn't coming all the way up to your mouth, your neck strap is too long. Adjust it as needed. Keep your bottom lip taut, but your mouth, jaw, and face relaxed. Place the tip of the mouthpiece against your lower lip. Close your mouth over the mouthpiece, creating an airtight seal with your lips. Rest your top teeth gently against the mouthpiece.  Don't bite down with your top teeth! Keep them relaxed. This is the proper mouth position for playing the sax. The position is called an "embouchure."

One-sentence summary -- Learn to play in a sitting position. Sit up straight and relax your neck and shoulders. Pull the neck strap over your head and adjust the length. Make a “C” shape with both of your hands. Place your right thumb under the lower thumb rest. Place your left thumb on the upper thumb rest. Hold the saxophone on your right side against your right leg. Bring the mouthpiece up to your mouth. Draw your bottom lip over your bottom teeth.

Problem: Article: Many people equate solitude with loneliness. They are not the same. Loneliness is subjected to you by other people. It can make you feel sad or miserable. Solitude, on the other hand, can be a time of rejuvenation and exploring the self. Here are just a few benefits of spending time alone:  Your brain has a break to rest and reboot. You are more capable of being productive. You learn more about yourself during moments of solitude. You have a better opportunity to problem-solve and weigh your options. You have an improved perception of yourself and therefore choose more healthy relationships. Take baby steps. If you are a person who tends to think solitude is boring or uncomfortable, it may not do well to force yourself into long bouts of solitude. In this case, it's better to slowly increase the amount of time you spend alone.  If you are always surrounded by others, simply schedule in about 30 minutes of solitude each day for a week. You might choose to drive or walk to work on your own instead of joining someone else. You might go for a hike alone or visit the beach on your own. Just commit to doing a short, 30-minute activity without anyone else present or demanding your attention. Take notes on the experience. Was it better than you anticipated? Were you bored? Why? Write down as many details as possible to better understand your aversion to being alone. Just because you find solitude boring doesn't mean it has to be. If you have periods of alone time approaching, make plans so that your solitude is filled with interesting and fulfilling activities.   For example, if you have to stay home on your own for a weekend, you could rent some cool movies, plan to do a creative project, or complete schoolwork during your alone time. To keep your energy revved, gather fun music, books, and other tools to make the time less boring. Preparing for moments of solitude can make the difference between the time dragging by and going by more quickly. Simply fill the hours with things you already love to do.
Summary:
See the benefit of solitude. Increase the amount of time you spend alone gradually. Prepare wisely for moments of solitude.
