Purchase a can of compressed air commonly used to clean electronics. Keep the nozzle about 1 inch (2.5 cm) from the screen and use short bursts of air. Blow the entire screen to loosen the dust. Compressed air can be purchased at electronics or big box stores. Make a loop of tape around your fingers with the sticky side facing out. Cover your fingernails and knuckles so they do not come into contact with the screen. Using wider tape will help you cover more area when you clean the screen. With the tape wrapped around your hand, press it onto the screen on top of the mark. Lift your hand away from the screen and continue patting it until the mark disappears. Switch between using the frontside and backside of your hand so you don’t put residue back on the screen.  Wear latex gloves to avoid getting fingerprints or scratches on the screen. If the mark is larger or is not coming up with the tape, you may have to use a stronger cleaning method.

Call your loved one, write him an encouraging card or letter, or visit him at home. This will show that you will stick by him no matter what. There are many different ways to stay in contact with the person you care about.  Make a point of seeing your loved one as often as you can without overwhelming him. If you're working, email him to check in. If you can't call every day, communicate through texting as often as you can. Your loved one may feel better, even just a little bit, if he spends some time out of the house. It can be monumentally difficult for a person suffering from depression to get outside in the first place. Offer to do something that your loved one might enjoy in the fresh air. You don't have to train for a marathon together. Just try going for 20-minute walk with your loved one. He may feel a little better after engaging in some physical activity outdoors. Some studies have shown that connecting with nature can reduce stress and elevate mood.  According to research, walking in green areas can help a person’s mind get in a meditative state, contributing to further relaxation and improved mood. Getting some sunshine will elevate a person’s vitamin D levels, which can contribute to improved mood. Even just sitting on a bench and soaking in some sunlight for a few minutes can be helpful. Your friend may get distracted, even momentarily, from his depression if he has something to engage in and look forward to. While you shouldn't force your friend to take up skydiving or learn the entirety of the Japanese language, encouraging your loved one to have some interests can help shift the focus away from his depression.  Find some uplifting literature for your friend to read. You can read together in a park, or discuss the book. Bring over a movie by your favorite director. Your friend can fall in love with a new range of movies, and you can keep your friend company while you watch. Suggest that your friend try to express his artistic side. Drawing, painting, or writing poetry can help your friend express himself. This is also something that you can do together. Whenever your friend achieves a goal, acknowledge and congratulate him. Even small goals, such as taking a shower or going to the grocery store, can be significant for someone who is depressed. You can encourage your loved one to try new things and get outside, but sometimes the best thing you can do is be there for all the mundane things. This can help your loved one feel less alone.  Being there for low-key activities like making lunch or watching TV can make a big difference. You can ease the depressed person’s burden by helping with the small things. This might be running errands, shopping for food and necessities, cooking, cleaning, or doing your loved one's laundry. Depending on the situation, giving your loved one healthy physical contact (such as a hug) can help him feel better.

Glucosamine may be effective in reducing pain caused by a number of different conditions. However, you should talk to your doctor before you start taking supplements to find out if they would be beneficial for you.  For example, you might say "Since my diagnosis of osteoarthritis, I've been reading a lot about glucosamine supplements as a possible treatment. Can you tell me about any risks and benefits to taking glucosamine supplements for me?" Keep in mind that there haven't been extensive studies on the effects of glucosamine supplements on many conditions. For this reason, your doctor may decide the potential benefit to you isn't worth the risk of trying them. There may be little benefit to taking glucosamine unless you have been diagnosed with a specific condition. For example, if you want to take glucosamine to treat your back pain, you generally should have a diagnosis of osteoarthritis. Absent a diagnosis, your doctor should rule out other causes for your back pain before you try supplements.  You also will want to talk to your doctor about the potential benefit. Most studies have shown only a modest improvement of symptoms in patients taking glucosamine supplements, so you may decide that such a small benefit is not worth the cost of the supplements. While glucosamine supplements typically are safe for most adults, they can cause problems if you have certain other medical conditions such as diabetes.  If you have diabetes, you may want to avoid glucosamine. It can adversely affect your insulin resistance and your blood-sugar levels. Another thing to keep in mind is that since glucosamine is harvested from shellfish, you shouldn't take these supplements if you are allergic to shellfish. Children under 18 should not take glucosamine supplements, which means you also shouldn't take glucosamine supplements if you are pregnant or planning to become pregnant. Glucosamine supplements also can interfere with drugs you're already taking to treat particular conditions such as depression or high blood pressure. Discuss this with your doctor in light of all medications you currently take, even those you only take on an as-needed basis. For example, you might say "If I take glucosamine supplements, will it cause more bleeding or bruising than I'm currently experiencing? I've read that glucosamine can increase bleeding in people like me who are taking warfarin." Glucosamine supplements may increase your risk of certain medical conditions such as heart disease or bleeding disorders. Ask your doctor about any conditions that you personally may be susceptible to if you take glucosamine supplements.  For example, if you are already at an increased risk for heart disease, your doctor may advise against prolonged use of glucosamine. The supplements may cause heart palpitations or other irregularities. If you have dry eyes or an increased risk of cataracts, glucosamine supplements may further increase this risk or cause cataracts to develop. Your regular doctor may not know about your eye health. If your ophthalmologist has told you that you are at risk for cataracts, let your regular doctor know. For example, you might say "My ophthalmologist told me I was at risk for cataracts, and I've heard taking glucosamine supplements can increase that risk. Would you still recommend I try the supplements to treat my osteoarthritis, or should I talk to my ophthalmologist first?" Since glucosamine supplements can increase the risk of bleeding, first tell your doctor if you have a bleeding disorder or are currently taking drugs such as warfarin that increase your risk of bleeding.
