Problem: Article: If you suspect that your dark knees are caused by dry skin, drink more water! In general, aim to consume at least 68 fluid ounces (2.0L) of water every day for healthy, glowing skin. If you don't see results from increasing your water intake, consider using a natural remedy or applying a moisturizer in addition to drinking water. If you've tried multiple methods to get rid of your dark knees but haven't had any results, make an appointment with a dermatologist. There, the doctor will be able to do tests and look at your knees to identify a likely cause for the dark skin in that area. Be sure to explain which methods you've used to try to get rid of your dark knees. Your doctor may be able to explain why your skin is darker in that area, and can offer more potent treatments for lightening the skin. Sometimes, individuals with undiagnosed or untreated diabetes will develop dark spots on their knees and shins. If you have spots that won't go away, visit your doctor to get tested for diabetes. This condition is called "diabetic dermopathy," and people often mistake these marks for age spots.
Summary: Increase your water intake to improve hydration. Visit a dermatologist to diagnose pigmentation issues or skin diseases. Get tested for diabetes if you have permanent dark spots on your knees.

Problem: Article: A prime rib roast with the bone in will have about 1 serving per pound, so plan to buy a pound of meat for every adult guest you're serving. Each guest will end up with about 6 ounces of meat. You certainly don't want to skimp, and the leftovers will be delicious, so you may want to buy an extra pound or two. The prime rib roast, also called a standing rib roast, is a fairly rare cut of meat, since butchers may need to sacrifice more common cuts of meat to get a large roast. Therefore, plan ahead and ask your butcher to cut you a prime rib roast in the size you need by a certain date. When you get the roast, it should be heavily marbled with a thick cap of fat and deep red meat that springs back when touched. You should be able to order a prime rib roast at your supermarket's meat department, but you may also try a local butcher. This roast is far more costly than other cuts of meat. If you are going to indulge in a prime rib roast, you may as well ensure you are getting a high grade of meat, like USDA Prime, if that option is available (most meat on the market is USDA choice quality, which has less fat marbling). You might also consider getting a dry-aged or grass-fed roast, both of which will yield beautiful results. You may do this at home or ask your butcher to do it for you. Cutting the bones away from the roast, then tying them back on with kitchen twine will make the roast easier to carve the roast once it's cooked. Slide a sharp knife between the top edge of the bones and the meat. Carefully cut them from the roast. You may leave the ends attached if desired. Wrap a piece of kitchen twine under the bones and around the meat, and tie it tightly. If you bought a less expensive cut of meat, you might want to apply a rub and let it refrigerate overnight so the flavors meld with the meat. If you bought USDA Prime beef, grass-fed beef or dry-aged beef, there's no need for a rub; you can cook your prime rib as soon as you get home from the butcher shop.
Summary: Calculate the amount of meat you will need. Order a prime rib roast. Cut the bones away from the roast. Refrigerate the meat until 3 hours before cooking.

Problem: Article: On the rear of your Roomba there is a tray that fills with dirt and dust as it vacuums (also called the "bin"). Press the button on top of this tray and remove it. Dump the contents of this tray into the trashcan. You should be able to see a red semi-circle inside the tray (which may be covered with gray dirt and dust). This is your filter. This filter will easily slide out of the tray, while remaining attached on one end. Slide this out, and knock any loose dirt/dust off into the trashcan. Attach the crevice tool (the long, thin attachment) to the hose of a regular vacuum cleaner. Then turn the vacuum on and use this attachment to remove dirt and grime from the Roomba collection tray and filter. Remove the crevice tool from your vacuum hose, and instead attach the brush tool. Turn your vacuum back on and go over the filter and tray once again. This time, pay extra attention to the surface of the filter, the rubber seals, and the vents on the back of the tray. When you are finished, snap the filter back into place.
Summary:
Empty your Roomba. Remove the filter. Vacuum the tray and filter using a regular vacuum and the crevice tool. Switch to the brush tool.
