Web browsers will record a history of sites visited by default. Your parents can check the history window to see all sites that were visited during a certain time period. Go into the settings of your web browser to delete the history. You can delete individual websites or clear the entire browsing history if preferred.   In Google Chrome, go to Settings, followed by the History tab to access History settings. You can also navigate Privacy settings here.   In Microsoft Edge, go to Settings and click on “Choose what to clear.” You can choose from several different types of files to clear, including browsing and download history.   While it’s possible to keep browsers from tracking history altogether, your parents will likely notice this setting when they attempt to access their own history. If the browser supports multiple users, make sure that settings are unique to each user. Otherwise, it’s best to delete only particular pieces of browsing history. Move files you are trying to hide, such as chat logs or passwords, into folders that require passwords to access. Remove the files from plain sight – the idea is to make finding the files as difficult and oblique as possible.   Rename the file into something innocuous that doesn’t give away the purpose of the file. “Passwords.txt” is a bad choice! Files can also be hidden in file folders for existing programs that otherwise have nothing to do with your chat logs or passwords, such as the data folder of a game application. Files can be made invisible with the “hidden” property on Windows OS. You can find this option under the Attributes field in file Properties.   Hiding files in a similar fashion on Mac OX is a bit more complicated – it may be easier to physically hide the file in this case.   Cloud services such as DropBox or OneDrive can store your files while also requiring additional login steps to help reinforce your security. Give your phone a password to prevent your parents from having access to your texts and phone call history. If you have to leave your phone laying around to take care of a quick errand, make sure to put the phone to sleep in order to enable the lock. It’s a good idea to keep your phone on your person at most times.   Use a unique password this is difficult or impossible to guess. Use a combination of letters, number and special characters when possible.  Consider fingerprint unlocking if your phone supports the feature. This provides an extra layer of security to your phone. For additional security, apps such as Snapchat can help you delete texts and photos automatically if you don’t want them to be discovered. Facebook, Instagram and other social media sites you use should be kept private. This will keep your parents (or others) from finding your account and freely viewing your messages and photos. You’ll have to add them to your network for them to see your activity.   Make a second, family friendly account if you are concerned about your family seeing certain activities, but don’t want to shut them out of your social accounts completely. Adjust your sharing settings. Facebook offers selective sharing options that can help filter out who gets particular access to your photos and posts. If your items or chat log does get find out, be ready with a believable excuse. Parents aren’t necessarily prone to believing such stories, but depending on the item and the nature of your friends, you might be able to create a convincing argument. Just don’t throw your friend under the bus!   A few examples include, "I'm keeping that for a friend,” or “A friend grabbed my phone and took these pictures.” Use a friend that your parents don’t know in your cover story. You don’t want your parents to give your friend’s parents a call and blow your cover.

Summary: Delete your web history. Hide files properly. Lock your phone. Keep your online accounts private. Have a cover story.


The normal resting heart rate for an adult is between 60 and 100 beats per minute (and for a child 70 – 100 beats per minute). However, a recent study indicated that a heart rate above 80 is one risk factor for obesity and diabetes. If your resting heart rate is between 60 and 80 beats per minute, it is likely to be categorized as healthy or normal. If it is, you might have a higher risk of cardiac disease and you should consult your doctor immediately.  A high resting heart rate means your heart needs to work harder to maintain a steady beat at rest. A high resting heart rate is considered a risk factor for ischemic cardiac disease, obesity and diabetes.  A 10-year clinical study found that adults whose resting heart rate increased from 70 to 85 beats per minute were 90% more likely to have died during the study than those whose rate remained below 70.  If your resting heart rate is high, take actions to lower it (see next section). A heart rate over 100 beats per minute is known as tachycardia. Some medications (such as thyroid medication and stimulants like Adderall and Ritalin) can raise your heart rate. Discuss with your doctor if you are concerned that the medications you are currently taking have increased your heart rate.  Environmental temperature and humidity can also temporarily increase your heart rate because your heart needs to work a little harder in these conditions. This does not mean your heart rate is high in normal conditions. Other causes of tachycardia include fever, hypotension, anemia, smoking, drinking too much alcohol or caffeine, electrolyte imbalance, hypothyroidism, and more. Having your rate be below 60 beats per minute doesn’t usually mean you have a medical problem. People who are very athletic or in good physical shape can have a resting heart rate as low as 40 beats per minute.  Some people have low heart rate by nature and there is nothing abnormal or unhealthy about this. Low heart rate is medically known as bradycardia. Some medications (such as beta blockers, sedatives, opioids, and many more) can slow down your heart rate. Ask your doctor if any of your medications cause low heart rate. Consult your doctor and ask if you need to take action due to low resting heart rate.

Summary: Assess if your resting heart rate is between the normal range. Assess if your heart rate is higher than 80 beats per minute. Assess if your resting heart rate is lower than 60.


They are saltwater shore-dwellers, and they need high temperatures to survive. Sand crabs live in rhythm with the tides, and it can be difficult to replicate the delicate littoral ecosystem in which they thrive. Furthermore, sand crabs feed on such a diverse diet that you may have a hard time giving them the variety they're used to. In the wild, sand crabs bury themselves deep in wet sand and catch plankton with their antennae. Replicate this process by filling your crab's habitat with beach sand, then pouring seawater over the sand a few times each day. Use any glass aquarium. Bear in mind that sand crabs cannot dig in sand that is too dry or densely-packed.  Try to bring the beach sand directly from the ecosystem where you got the crab. Local beach sand is more likely to contain the insects and microorganisms that your crab needs. Sand crabs naturally gather in shoals, so it should be okay to put several sand crabs in the same tank. Remember, however, that large crabs like to eat smaller crabs. Homemade saltwater will not do; it needs to contain algae and plankton. You can buy plankton, algae, and aquarium-grade seawater at some aquarium-supply and exotic pet stores. Be warned that these supplies can be expensive. Understand that this tactic is a short-term experiment to study the behavior of a sand crab. It is not necessarily a sustainable, long-term way to keep a sand crab as a pet. If you only need to study the sand crab for a short time, consider returning it to the wild when you're done. Sand crabs are difficult—sometimes nearly impossible—to keep as pets. If you are looking for a crab that's easy to raise and feed, consider getting a hermit crab. Do your research, create a habitat, and learn to care for hermit crabs. Aquarium hermit crabs thrive on practically any food, from algae and leftover fish food to beef, eggs, and vegetables. In the wild, hermit crabs have been known to eat leaves, fruit, and even wood. You can also buy commercial hermit crab food that mimics the crab's natural diet.
Summary: Consider the challenges of removing sand crabs from the wild. Set up a tank with fresh beach sand and seawater. Regularly refill the tank with seawater. Consider getting a hermit crab instead.
