In one sentence, describe what the following article is about: You'll have a relatively easy time finding typewriters at antique stores, but when purchasing from antique stores, you should be wary of overpricing. Antique store owners are often aware of the value of their vintage typewriters, so they may overprice their typewriters or try to sell you one that's in bad shape. Always ask to use the typewriter before purchasing. While an everyday flea market probably won't have vintage typewriters, antique flea markets often do. Because of the volume and nature of the wares, these one-day sales can be better deals than most other reliable vintage stores. If you're on a budget and don't have a specific typewriter in mind, this could be the place for you! Donation stores like Goodwill and Salvation Army may have old typewriters that have been donated by someone who does not need or want it anymore. While there is a good chance that these typewriters are partially or completely broken, there's also a chance you'll find that perfect, hidden typewriter in the back of the store, just waiting for you. Finding a typewriter at a garage or estate sale can take a lot of patience, but you can usually get a great deal if you do find one. If you're hunting for vintage typewriters in these types of sales, make sure you arrive early! There will probably be others in your area who have the same idea.
Summary: Shop at antique stores. Find flea markets that specialize in antiques. Check out donation stores. Visit garage and estate sales.

In one sentence, describe what the following article is about: This test requires you to provide a stool sample so your doctor can test for small amounts of blood in your feces. Depending on which type of FOBT you undergo, you may need to avoid certain foods before getting the test. Your doctor can outline the details of the test and any steps you need to take before you provide a sample. Your sample will then be sent to a lab for testing and your doctor will receive the results of the test in a few weeks. For this exam, your doctor will exam your rectum and abdominal for any lumps. If they notice any lumps, they may perform a more detailed test like a sigmoidoscopy or a colonoscopy. You may find getting this test done a bit uncomfortable but your doctor should walk you through the exam and make you feel at ease. The DRE usually takes no longer than a few minutes to complete. This procedure uses a sigmoidoscope, a flexible tube with a lens, to look into your rectum and colon lining. The sigmoidoscope will need to be inserted into your anus, so your lower colon must be cleared of stool beforehand. You are not usually sedated when undergoing this procedure, though you can ask your doctor to do so if you’d prefer. A colonoscopy is done by inserting a colonoscope, a flexible tube with a lens, into your anus so your doctor can check your rectum and colon. Your doctor can also remove any abnormal growths in your colon, upper colon, or rectum for further testing.  You are usually under sedation during the colonoscopy to ensure you do not experience any pain or discomfort. Your doctor will recommend that you do a deep cleanse of your colon before the test. Make sure you prepare properly for the colonoscopy so it goes well. A virtual colonoscopy uses x-ray equipment and a CT scanner to take pictures of your colon and rectum form outside your body. This screening method may be a good option if you’d do not want have to have a standard colonoscopy or you cannot have one due to other health issues.  You will still need to do a thorough cleanse of your colon before the test for it to work. If any abnormal growths are found during the virtual colonoscopy, your doctor will have to perform a standard one to remove them. Some healthcare providers do not cover the cost of a virtual colonoscopy. Check with your insurance provider before you get this test done if you are worried about the cost. This screening option requires you to take an enema with a barium solution. The solution will help to outline your colon and rectum when you undergo an x-ray. This option is not as detailed as a colonoscopy but it can be ideal if you have medical issues that prevent you from having a colonoscopy.
Summary: Get a fecal occult blood test (FOBT). Have a digital rectal exam (DRE). Allow your doctor to do a sigmoidoscopy. Let your doctor perform a colonoscopy. Try a virtual colonoscopy for a less invasive option. Get a double-contrast barium enema if you cannot get a colonoscopy.

In one sentence, describe what the following article is about: Lay the rhubarb along a sheet of aluminum foil and fold the edges over the stalks. Don’t seal the edges completely. Leave a small space for air to get in and out.  Tightly wrapping the stalks traps in moisture and ethylene (a hormone that ripens vegetables) so your rhubarb will go bad faster.  Don't wash the rhubarb until you're ready to eat it. The best spot in the fridge for your rhubarb is the vegetable crisper drawer because it has the highest humidity. It won’t dry out the stalks. After 1 month or if you notice moldy spots, toss any uneaten rhubarb. Keep your refrigerator at a temperature of 32 to 40 °F (0 to 4 °C) for storing rhubarb. To freeze the rhubarb properly, first rinse it and pat it dry with a paper towel. Then chop the rhubarb into small pieces and put them in an airtight container or resealable freezer bag. Place the container in the freezer to use within 1 year.  If you’re using a freezer bag, remove any excess air before sealing it shut. Label your container or bag with the date and the contents using a permanent marker. Frozen rhubarb is great for smoothies or baking.
Summary:
Wrap the rhubarb stalks loosely in aluminum foil. Place the wrapped rhubarb in the fridge for 2 to 4 weeks. Freeze the rhubarb for up to 1 year if you aren’t using it right away.
