In one sentence, describe what the following article is about: Each day take a quick look at your case to see if it has developed any cracks. Even a crack in the lid threading can let bacteria into the interior well area. Or, if you drop your case and it sustains damage, you may want to consider replacing it early. Take out a fresh, clean toothbrush used expressly for this purpose. Get out your bottle of contact solution as well. Wet the toothbrush with the solution and scrub out the interior and lids of your case. When you are done, rinse it out with solution and let your case air dry.  Some people contend that boiling your case is the best weekly cleaning method. If you would like to try this, you will need to dip your case into boiling water for at least three minutes. Be very careful to avoid burns. Other people recommend that you run your case through the dishwasher.  If you detect visible dirt or hard biofilm on your case during your weekly cleaning, you may want to consider replacing it early. When you get a new case, turn it over and write the date on the bottom with a sharpie. This way you’ll know when you need to replace it. Bacteria begins to accumulate in a case after just one week of use, so three months of usage is really the limit. Don’t wait until your doctor gives you a replacement. You can purchase a new case at the pharmacy or grocery store.  In one study, 47% of contacts users admitted to never replacing their lens case.  You may be tempted to keep using your case if it doesn’t look dirty or worn. However, be aware that most bacteria are not able to be seen by the naked eye. Researchers have been developing a contact lens case that repels bacteria. The case is currently being tested and could be on the market shortly.
Summary: Throw away your case if it is damaged. Clean your case weekly. Replace your case every three months. Purchase a bacteria-resistant case.

In one sentence, describe what the following article is about: If you don't already have iTunes, you will probably want to download and install it before beginning. Though it's possible to add music to your iPod without iTunes (see above), this is by far the most common way to do so. In addition, iTunes is free, simple to download and install, and offers a variety of helpful features, including in-program access to the iTunes Store and options for automatically syncing your iPod library to the library on your computer. To download iTunes, simply visit iTunes.com and click the "Download iTunes" link in the upper right. Supply your email address and click "Download Now" to start the download. Your new iPod should be packaged with a white USB cord. This cord allows you to transfer media between your computer and the iPod. Connect the skinny, flat end of the cord to your iPod (there should be a corresponding port on the bottom of the iPod) and the other end to one of your computer's USB ports to begin. Note that models of iPod other than the standard version (like, for instance, the iPod shuffle) will have cords with differently-shaped plugs. However, all varieties of iPod cord will have one end that plugs into a USB port. When you connect your iPod, iTunes should launch automatically. If it doesn't, you may open it manually. Within a few moments, iTunes should recognize the iPod. You will know this is happening if you see the trademark Apple logo appear on your iPod without prompting. You may also notice a progress bar appear at the top of your iTunes window indicating that iTunes is downloading data required to interface with your iPod. Wait for iTunes to complete before proceeding — this may take several minutes.  If iTunes doesn't seem to be recognizing your device automatically, don't despair. iTunes is somewhat notorious for experiencing problems with new devices. Try disconnecting your iPod and reconnecting it, opening and closing iTunes, and restarting your computer before reaching out to iTunes support. Additionally, if your iPod is low on power, you may need to wait for it to charge off of your computer's power supply for several minutes until iTunes is able to recognize it. Eventually, iTunes should automatically launch a large welcome message. Click "Continue" to proceed. Next, you'll see a screen that says "Sync with iTunes". Click "Get Started" on this screen. You will be brought to a screen that presents you with a variety of options, including:  Updating your iPod software to the latest version. If your iPod software isn't current, clicking "Update" will download and install the latest version of the software. This keeps your iPod up-to-date with all of the features and security fixes. Creating a backup of your iPod data. If this is the first time you're using your iPod, you won't have any data to back up, but choosing an automatic backup location (either your computer or the iCloud) ensures you won't have to worry about it in the future. To exit the current screen, simply click the blue "Done" button in the top right of the iTunes window. When you do this, you'll be brought back to whatever you were looking at in iTunes before you began. From here, you can add music to your iPod as you normally would (see "Using iTunes" section above).
Summary: Download and install iTunes. Connect your iPod to your computer. Wait for iTunes to recognize the iPod. Follow the prompts that display. Click "Done".

In one sentence, describe what the following article is about: Try to pick them so that the stems are all approximately the same length.

Summary:
Pick three flowers with long stems. Hold the flowers together just below their heads. Separate the stems.
