What is a one-sentence summary of the following article?
" People planning suicide may take measures to settle their affairs before proceeding. This is a major warning sign since someone tying up loose ends probably has a suicide plan in place. Someone who is suicidal may do one or more of these to get ready:  Give away their prized possessions. Make financial arrangements, such as suddenly writing a will.  Say goodbye to loved ones. A person that is considering suicide may suddenly make a point of saying a heartfelt goodbye at odd times. Since suicidal people feel no reason to live, they may take risks that could lead to death, like driving recklessly or while impaired. Here are few potential signs to look out for:  Excessive use of drugs (legal or illegal) and alcohol. Reckless driving, such as driving too fast or under the influence. Unprotected sex, often with multiple partners. It's a good idea to investigate whether the person has recently purchased a gun, or might be stockpiling legal or illegal pills. If someone seems to be collecting medication or purchasing new weapons out of the blue, it's important to act quickly. Once their plan is in place the person could commit suicide at any time. Avoiding friends, family, or coworkers is common among suicidal individuals, who often quietly withdraw from normal social interactions. Take action, rather than just listening to someone who says "I just want to be left alone." If someone suddenly stops going to their weekly pick up basketball games or their favorite game nights this could be a warning sign. Skipping out on going out or taking part in activities they normally enjoy could indicate that someone is feeling unhappy, depressed, or possibly suicidal. Suicidal, depressed individuals often have little energy for basic mental and physical tasks. In particular, be on the lookout for:  Unusual difficulty making ordinary decisions. Loss of interest in sex. General lack of energy, behaviors like staying in bed all day. If the person in question is a teenager, watch for additional common warning signs and possible triggers for teens. For example:  The teen is in trouble with their family or the law. Life circumstances like a recent breakup with a boyfriend or girlfriend, not getting into their college of choice, or the loss of a close friend. Lack of friends, trouble in social situations, or withdrawal from close friends. Self-care issues, like insufficient eating or overeating, hygiene issues like infrequent showering, or lack of concern about appearance (e.g., a teenager who suddenly stops using makeup or dressing well). Drawing or painting scenes of death. Sudden shifts in their normal behavior like a drastic drop in grades, drastic personality changes, or rebellious actions may also be warning signs. Conditions like an eating disorder such as anorexia or bulimia can also lead to feelings of depression, anxiety, and possibly suicide. A child or teen being bullied or bullying others may also be at a higher risk for suicide.

Summary:
Look for signs of "tying up loose ends. Look out for reckless, dangerous behavior. Look for the means to commit suicide. Be aware of social withdrawal. Note any extreme changes in routine. Be aware of unusually lethargic behavior. Watch for warning signs in teens.
