In one sentence, describe what the following article is about: It should be obvious that an improperly-sized bike can lead to back pain or other physical issues, but many people select a new bike based on price point and tend to downplay the importance of the bike's dimensions and ergonomics. Ideally, a bike should be customized to your body, but that can get pretty expensive. A more economically friendly alternative is buying a bike from an actual cycle store (not a big department store) and asking the salesperson about proper sizing.  Once you've narrowed down the style of bike and the size of the frame, ask to take the bike on an extended test drive (at least 30 minutes) and see how your back responds to it.  Choosing a bike that is too big will cause you to hunch over too far when reaching for the handlebars, which can eventually lead to back pain. For those with low back conditions, a reclining bike (also called a recumbent bike) may be the best bet. Although the bike's frame height is important, especially for being able to dismount safely, the height of your saddle is even more paramount. Saddle height is determined by how long your legs are and should be positioned so that when the pedal is at the bottom of the stroke (nearest the ground), your knee should have a slight bend in it — between 15 – 20 degrees of flex ideally.  Your hips and buttocks shouldn’t move sideways while peddling and you shouldn’t have to stretch your legs at the bottom of each pedal stroke — stretching too far with your legs puts strain on your low back. Adjusting the saddle angle is also important. Positioning it horizontal (parallel to the ground) suits most people, although people with chronic back conditions or sensitive perineum areas may feel more comfortable with the saddle tilting somewhat forward. The bike's handlebars should be adjusted to a height at which you can comfortably reach them from an upright position, while having your elbows slightly bent. This is usually a personal preference, but the handlebar height is often even with or up to 4 inches (10 cm) below the saddle height, depending on back muscle flexibility. The angle of the handlebars is not adjustable on many low-to-mid-range bikes, but if yours is, try different settings and see how your back responds. Increasing the angle acts to raise the handlebars and bring them closer to your body (allowing you a more upright posture), which may be helpful for preventing back strain.  Novice and occasional cyclists should keep their handlebars at the same height as their saddle. Seasoned cyclists generally keep their handlebars a few inches below their saddle height to be more aerodynamic and faster, but it requires decent flexibility within the muscles of their backs. Almost all modern bikes (at least mountain bikes) have some sort of suspension or shock-absorbing accessories. Shock absorption is very important for the well-being of your spine, especially if you mountain bike on rough terrain and are getting frequently jarred. The smoother your ride is, the less musculoskeletal pain you're likely to develop. Get a bike with front shocks at the very least, but consider bikes with full suspension somewhere underneath the seat if preventing back pain is important to you.  Other forms of shock absorption on a bike include: thick knobby tires, heavily padded saddles and cushioned biking shorts. Most suspension accessories are adjustable, so ask a qualified salesperson for assistance if you need to. Road racing bikes tend to be especially light and rigid, but don't come with suspension.
Summary: Buy the appropriate size of bike. Make sure the saddle is the right height. Adjust the handlebar height and angle. Get a bike with suspension.

In one sentence, describe what the following article is about: Seal the lid as tightly as possible. Place them away from any areas with open flames. Mineral spirits ignite at 105 to 145 °F (41 to 63 °C). Mineral spirits do not “go bad,” so it is not necessary to dispose of them after you use them as paint solvent. Allow the mineral spirits to settle, letting the paint sink to the bottom. The best thing to do with mineral spirits is to buy low quantities and reuse them for decades. They evaporate very slowly. Label them immediately for reuse. Pour the remaining paint at the bottom into cat litter.  Follow the next method to dispose of the paint and kitty litter properly. You can buy containers that can safely store solvents at art supply stores, hardware stores and on the Internet. Not all plastic containers are acceptable for use, because the solvent may wear down and break the plastic over time. This solvent can be retained for use with oil-based house paint or art paints. Add small quantities until the paint reaches the consistency of your choice. Add more medium to your paint, if you feel you may have added too much solvent. Overly diluted paint may not bind to the canvas. However, using more paint medium will reverse the effect. You can extend the life of the spirits if you must get rid of them.
Summary: Keep mineral spirits in the original container after you are done using them. Leave the mineral spirits alone in their sealed container for months at a time. Remove the lid, pour off the clear mineral spirits into a thick, new waste-safe container. Use mineral spirits to thin oil paints. Call a local construction co-op, art school or lifelong learning center to inquire about donating extra mineral spirits.

In one sentence, describe what the following article is about: This will ensure that your current directory is updated to match that of the .dll file. If you are deleting multiple .dll files, they may not be in the same location.   This will open the Command Prompt app, which allows you to interact with the operating system via user-entered commands. If you're using Vista or later, you'll need to boot Command Prompt in Administrator Mode. To do this, click "All Programs" in the Start menu, select "Accessories", right-click the "Command Prompt" icon, and select "Run as Administrator". This will reset your Command Prompt execution to your current directory, where the .dll file is located. This command finds and unregister  your targeted .dll file. Exclude the quotation marks and the apostrophes; for "(filename)dotdll", insert the name of your target .dll file and the .dll extension. Your .dll file should now be ready for deletion!  This will send your .dll file to the Recycling Bin, from which you can delete it permanently.
Summary:
Open your DLL file's location. Open the Start menu. Click "Run". Type "cmd" into Run's text field, then click "OK". Type "cd" without the quotes and press ↵ Enter. Type "regsvr32 -u (filename)dotdll" into Command Prompt. Press ↵ Enter to unregister your DLL file. Locate your DLL file in its directory. Right-click your DLL file and select "Delete".
