Article: To stay mentally and physically quick, you must take care of yourself. Exercise at least 3 times a week, or more if possible. Exercise increases blood flow to your entire body, including your brain. Your body will thank you with speedier reaction times and plenty of endorphins. If you are not used to exercising, work your way up with shorter simpler exercises. Start with a 15 to 30-minute walk, then move on to jogging or swimming. Eat healthy, balanced, and consistent meals. Eating right gives your body the fuel needed to perform at its best. Work some eggs and spinach into your diet; they’re super foods for the brain, both containing the amino acid tyrosine, which has been shown to increase reaction speeds. Conversely, drinking alcohol or using illegal substances can slow your reaction speeds down. If you are tired, you’ll respond sluggishly no matter how well you eat or exercise. Make sure to get at least 8 hours of good, solid, undisturbed sleep a night. This will allow you to stay alert for longer periods.  How much sleep you need will depend on your personal needs. Typically, this will be between 7 and 9 hours. Don't get too much sleep either. If you wake up early, then go and start your day. Sleeping in can make your body and mind sluggish. It is very tempting to down a cup of coffee whenever you need speed and focus on a task. Be careful, though, because this one can backfire! Control your caffeine consumption so it boosts your response times without making you fidgety and scatter-brained. Stick to just 1 cup prior to working on a task requiring quick responses so you don’t get jittery and lose focused. This also goes for energy drinks as well. Don't ditch the coffee only to replace it with a canned energy drink. Some medications can slow down your response time and reflexes. Or, you may even experience dizziness or blurred vision. If you need a high reaction speed, make sure to talk to your pharmacist or your doctor about how your medications might impact your abilities.  This is an especially important step to follow if you are about to drive a motor vehicle. Even in good conditions, you’ll want to have sharp reflexes. Don’t get discouraged if you can’t change your medications at all. By working on your mental and physical agility, you can still improve your reflexes.
Question: What is a summary of what this article is about?
Exercise. Eat right. Get enough sleep. Limit your consumption of caffeine. Monitor your medications.

Problem: Article: One of the main ways to build bridges instead of walls is by recognizing shared humanity. That means, we all have much more in common than not. Find a way to relate to others and you’ll limit judgments. If you catch yourself criticizing or judging others, find three things you have in common with that person or the situation. For instance, your partner didn’t stand up for themselves at work. Rather than judging them as weak, think about three different times when you had trouble speaking up for yourself. Acceptance is necessary for overcoming a judgmental attitude. Acceptance implies letting a person be who they are; not trying to change them. When you are able to recognize that another person is human—and all humans make mistakes—you can choose to accept the person.  Acceptance also implies lack of total control. When you judge, there’s an underlying desire to control others, or make them into who you would like them to be. Acceptance means allowing them to be who they are, and recognizing that you have no power to change them anyway.  To demonstrate acceptance, you might remind yourself "I am not in control of who she is. Her behavior does not reflect on me. I can help her by being loving and accepting." Sometimes we get stuck in the mud of flaws and refuse to see the good in others. Counteract this negative tendency by purposely identifying the positives in those around you. Do this daily. Start a practice of listing 10 positive strengths about yourself and others each day. This helps you train your mind to see the good rather than the bad. Your judgments of others often come from an inner need to avoid your own flaws. People who judge others are also often very judgmental of themselves. Don’t use others’ problems to cover up your own, or place yourself on a pedestal. If you notice yourself being judgmental, remind yourself that you are flawed, too. Therefore, you have no place to judge.  Increasing your self compassion will help you gain a natural compassion for others. You might repeat silently, “I am human. I make mistakes, too” when you find yourself judging others. If you catch yourself being judgmental, try to override the habit by immediately apologizing. When you apologize you reinforce the action as being inappropriate and you extend an olive branch to those you judged.  An apology can be simple and straightforward. Say, "I'm sorry, Charlie. I judged you just then and I shouldn't have. I hope you can forgive me. I'm working on overcoming my judgmental tendencies." Work on your openness and honesty. By being candid about your judgmental nature, you can usually take note of it and help decrease it.
Summary: Focus on similarities, not differences. Accept others’ flaws. Celebrate others’ strengths rather than dwelling on faults. Recall your own shortcomings. Apologize to those you judge.

People may notice that you two aren’t friends anymore and ask you what went down. It’s okay to say something non-specific, like “we just kind of drifted apart,” but don’t get into the details. Talking trash about your former friend is mean and immature, no matter what happened to cause the friendship to fall apart. If your friend gets nasty, spreading rumors or gossiping about you on social media, try not to engage. There’s no point in dragging things out or defending yourself to someone you don’t even want to be friends with anymore. But most importantly don't do the same to her. If you talk behind somebodies back, word will most definitely come out. If anything, it shows that you made the right decision. Things might be awkward for a while, and your friend may be angry or hurt, but treat her with kindness and respect. Remember that this is someone  who was once your friend—maybe even your best friend—so honor what you had. Don’t do the look-of-death thing or straight-up ignore her. Just give her a small smile or nod of acknowledgment and move along. If she talks to you, turn it into a friendly conversation that won't lead into getting closer. Try to keep talks short until she feels as if you don't seem interesting. Ending one friendship may cause ripples if you’re part of the same group. Mutual friends may take sides, ask you to reconcile with her, or even get angry.  Try not to get upset if some of your mutual friends feel they need to take sides. This may happen, and it’s going to hurt, but those people are petty and looking for drama, and you don’t need them in your life.

One-sentence summary --
Don't gossip if people ask you what happened. Be polite when you see her. Don’t get drawn into any drama if your mutual friends get upset.
