In one sentence, describe what the following article is about: Noni juice is a herbal supplement. It’s always a good idea to check with your doctor to make sure it’s safe for you to drink. Noni juice is said to have many wonderful health benefits, but these are unproven and can come with side effects. Stay in contact with your doctor in case you experience a negative reaction to the juice. A tenth of a cup (about 30 mL) is a common starting dosage. You only need a shot of the juice per serving. As you get used to the juice, you can increase the dosage or have a second dose later in the day. Take no more than three cups (750 mL) a day. For noni extract in capsule form, limit yourself to 500 mg a day. Read the label to find out how much extract is in each pill. Noni juice has been used in the past for abortions. Although there’s no conclusive evidence proving that noni will harm fetuses or babies, it’s best to play it safe. Cut noni out of your diet for the time being. Anyone with liver or kidney diseases should stay away from noni. Potassium and other components of noni juice will make these problems worse. Speak to your doctor to find alternative options. Unexplained weight loss, fatigue, and nausea are common symptoms of these diseases. You may see skin yellowing with liver disease. Kidney disease may come with swelling in the face, hands, and feet. Noni gives your body a high dose of potassium. High potassium, or hyperkalemia, affects your heartbeat and muscle operation. If your potassium level changes or you start experiencing problems, stop drinking noni juice. Symptoms of high potassium include fatigue, numbness, nausea, chest pain, and heart palpitations.
Summary: See a doctor before drinking the juice. Start with small quantities of noni juice. Avoid noni juice if you are pregnant or breastfeeding. Stop drinking noni juice if you experience liver or kidney problems. Avoid noni juice if you have a high potassium level.

In one sentence, describe what the following article is about: There are some life events that make a person more likely to attempt suicide. If you know what to look for, you will have a better chance at preventing it from happening. Pay attention to the stressors going on in the person’s life and consider whether they might be placing the person at risk for suicide.  Make a mental note of whether the person has attempted suicide in the past. You may have to just ask, “Have you ever considered suicide?” Be aware if anyone the person knows has recently died, especially from suicide. The death of someone close to them can cause some people to consider suicide. This is especially true for teenagers.  Find out if there is history of suicide in their family. You may have to ask them directly or ask one of their family members. Pay attention if the person is or has been a victim of violence, bullying, humiliation, or abuse.  These situations can lead a person to view suicide as an option. Notice if the person has suffered a loss such as being laid off from work, a divorce or break-up, or even if their reputation has been severely damaged. Be alert if the person has a serious illness such as chronic pain or exhaustion with no end in sight. Sometimes people view suicide as a way to end their pain. Often a person considering suicide will give verbal clues about what they are planning. Knowing what phrases to listen for can help you recognize when the person is suicidal and help them before they go through with it.  Be alert for phrases that suggest the person feels they are a burden on people like, "Everyone is better off without me" or "They won't have to deal with me". Listen for signs that they feel no one cares about them or understands such as: "No one cares what happens to me"; "Nobody gets me"; or "You just don't understand!" Pay attention if the person indicates that they don’t see any point in living by saying things like, "I have nothing to live for", "I'm just so tired of life". Notice if they say something hopeless such as: "It's too late now. I can't go on"; "There is nothing left to do"; "What's the use"; or, "I just want the pain to stop." You can help prevent a suicide by paying attention to how the person feels and is acting emotionally. There are some emotional warning signs that the person might be contemplating suicide.  If they aren’t expressing their feelings, then ask them. You might say, “How are you doing emotionally? How do you feel?” Have they expressed a sense of personal failure, hopelessness, or guilt? Do they seem depressed, anxious, or overwhelmed? Notice if they are crying a lot or are upset all the time. Make a note of whether they are moody or irritable. Do they get angry at things that didn’t bother them before? Sometimes people may even seem calmer and happier than they have been in a while. They may be looking forward to an end to their pain and suffering. Pay special attention to this sign, especially if they have been feeling down for a long time. People that are thinking about suicide may show behavioral warning signs. Paying attention to how the person is acting can help you prevent their suicide.  Pay special attention if the person is talking, reading, or writing about death/suicide. Notice if they seem disinterested in things they used to enjoy. Have they stopped participating in regular activities? Giving away personal possessions, especially items of value, for no reason is a sign someone might be considering suicide. Buying weapons or pills and visiting places like bridges, overpasses, rooftops, etc. may be signs a person may be planning suicide.
Summary: Pay attention to risk factors. Listen for verbal warnings. Notice their emotions. Look for changes in behavior.

In one sentence, describe what the following article is about: It bears mentioning that, though people commonly use the word "octagon" to refer to a regular octagon (one with sides and angles that are the same size), this is not, strictly speaking, the only kind of octagon that exists. Any shape with eight sides is an octagon by definition, just not a regular octagon. Thus, making a shape with eight sides of different lengths, rather than of the same length, produces an irregular octagon. As with their side lengths, octagons don't necessarily have to contain angles that are all 135o. As long as your shape has eight sides, angles of smaller or greater size than 135o can be used, resulting in an irregular octagon. The exception to this rule is for angles of exactly 180o. Generally, the two line segments that make up such an angle can be considered a single edge in a polygon. It's also worth nothing that special types of polygons called star polygons can have lines that cross over one another. For instance, an ordinary five-pointed star is drawn in this way from five lines that intersect each other in multiple locations. Similarly, it's possible to make an  eight-pointed star from eight lines of equal length. It's also possible to make eight-sided shapes with sides that intersect without making a tidy, symmetrical star shape. These shapes can be generally be considered "special case" octagons.
Summary:
Use eight sides of varying length. Use angles of varying size. Use sides that intersect themselves.
