Problem: Article: While taking blood thinners may increase your risk of bleeding if you are injured, it is necessary to stay on these drugs to avoid other serious complications, such as a stroke, pulmonary embolism, or myocardial infarction. Make sure that you continue taking your medication unless your doctor advises you to stop taking it. Because anticoagulants decrease your body's ability to form blood clots, your risk of excessive bleeding is significantly higher. You can reduce your risk of injury by minimizing your contact with sharp objects and avoiding contact sports/activities. Exercise extreme caution while using knives, scissors, and razor blades. You may want to consider switching to an electric razor if you shave any part of your body. Be cautious when you trim your fingernails and toenails to prevent excessive bleeding from your cuticles. Stick with low- and non-contact activities like swimming and walking. Talk to your doctor before beginning any new exercise regimen or sport/activity. You can also discuss your medication options with your doctor to find one that poses the lowest risk of excess bleeding if you are injured. If you are taking anticoagulants, you'll need to exercise great caution to avoid injuring yourself. This includes taking precautions when you're doing work around the house or simply traveling in your community. Wear a protective helmet anytime you roller-skate, skateboard, or ride a bike or scooter, or choose a safer activity. Choose shoes and slippers with non-skid soles to reduce the risk of falling. Make sure you wear shoes and gardening gloves any time you do yard work. You can also wear protective gloves when you handle sharp tools to prevent injury. You may not think of brushing your teeth as a dangerous activity, but if you're taking anticoagulants your gums could bleed excessively. You can take precautions against this by treating your gums gently and making minor changes to the ways you clean your teeth. Use a soft-bristled toothbrush to reduce the risk of injuring your gums. Avoid toothpicks. Instead, clean your teeth by carefully using waxed dental floss. If you're not getting your blood levels checked regularly by a doctor, there's a risk that you could be taking too much or too little of your medication. In the case of blood thinners, taking too high a dose carries a risk of excessive bleeding and bruising. You will have to get your blood levels checked regularly for certain drugs, such as Warfarin. Weekly lab work will help to ensure that the medication is working properly and it can also prevent overdose or sub-therapeutic levels. Excessive bruising, bleeding gums, nosebleeds, heavy menstrual bleeding, and prolonged bleeding from minor injuries are all common problems associated with taking too high a dose of blood thinners. Have your blood tested regularly by your doctor and inform your doctor if you experience any excessive bleeding or bruising. Some blood thinners are not safe to take if you are pregnant or plan on becoming pregnant. They may carry an elevated risk of fetal bleeding and birth defects. For this reason, doctors typically recommend that women who plan on becoming pregnant switch to a blood thinner that will not cross the placenta and affect the fetus. This switch should be made prior to becoming pregnant. Warfarin (Coumadin), a common blood thinner, is not safe to take during pregnancy. Heparin, another common blood thinner, will not cross the placenta and is therefore considered generally safe to take during pregnancy.
Summary: Avoid stopping your medication. Prevent injury. Use protective equipment. Be gentle on your teeth and gums. Watch for signs of overdose. Understand the risks associated with pregnancy.

Many hidden cameras require bright light to work their best. At the same time, they are unable to clearly record images when such light is shone directly into their lenses. Position your camera facing away from major light sources. Make sure that whatever you're trying to film is well-lit at the specific time of day it's most likely to be seen. A hidden camera does you no good if your target knows it's there. There are two major strategies for making sure hidden cameras stay hidden: Make the camera itself small and difficult to see. In other words, a camera with a tiny visible lens that is put in a discreet location. This is what comes to mind when most people think of hidden cameras. The truth is this type of disguise is much easier to spot since an effective hidden camera must have an unobstructed view of whomever it's watching. If the lens can see a person, the person can see it. Disguise the camera as an everyday object. Tissue boxes, coffee makers, alarm clocks, digital picture frames, wall hooks, and even plug-in air fresheners are all examples of commercial nanny cams that blend seamlessly into the home environment. A person is much less likely to see a lens that was designed to look like a button compared to a separate camera that has simply been hidden. There are hundreds of different commercially available hidden cameras and each comes with its own particular set of installation instructions. If you've purchased your camera secondhand, try looking up its model number online. The user manuals for many electronic devices are freely available for download. Don't forget to install any necessary software. Most hidden cameras rely on external software to function. This can be a program that was bundled with your camera or one made by a third party available for download. Some programs are even meant to be installed on you smart phone for you to keep watch while on the go. It's very important to check your camera's functioning, especially if it's motion- or sound-activated. It's a good idea to make sure that your camera switches on when given the right stimulus. How you do this will vary greatly depending on your particular camera and any companion software. Start by waving your hand in front of the camera to see if your camera records at all. Check your computer or the camera's internal storage to see whether or not this motion was recorded. Try mimicking a real world scenario, such as walking into the room, to see if the camera records your actions with appropriate image quality. Test it again in a few hours and yet again a few days later to ensure that it continues to work. Even if setup was a breeze, you will likely need to do some maintenance from time to time to make sure your camera is still working. If your camera runs on battery power, you will need to either swap in fresh batteries or recharge the device. Consult the owner's manual for advice on how often this should be done. If no suggestion is provided, make a note of how quickly it takes the battery to discharge. Clean out the camera's memory regularly. For cameras with limited internal storage, you should review and purge footage often. If your camera is hooked up to a server with a vast storage capacity, you may never need to do this. Like all electronics, your camera may break or wear down without you immediately knowing. Periodically double-check your camera to make sure it's still working.
