In one sentence, describe what the following article is about: Other back cracking methods can be very dangerous and are not professionally recommended. Stick to the gentle massage method used by chiropractors to reduce the risk of complications. Aggressive methods, like the bear hug or methods that involve lifting, have been linked to medical trauma. The method outlined here is based on chiropractor guidance and is safer to perform. However, it's always best to see a professional. The person should lie on their stomach on a flat surface. Something like a bed, table, or even the floor would work well. Back cracking, when done safely, is really more of a gentle massage than an attempt to push someone's back too harshly. Start by using one hand to gently press down on the person's buttocks and the other hand to press down on the person's upper back. Make a series of gentle pressing motions for a few seconds to start. Place one hand on the person's lower back, just above their buttocks. Tuck your other hand just under the pelvis. Gently press down on the lower back while lifting upwards slightly on the pelvis. After working the pelvic bones, the person should lift their legs while remaining on their stomach. This works best if you have an actual chiropractor table and can lift the bottom half of the table up and down lightly. However, as you likely don't have such a table, you can try having the person lift both legs up and down slightly at the same time. This should be a gentle, rocking motion, as it will help with the back cracking process. Press on the part of the back just above the buttocks on the bottom of the spinal cord. Keep pressing until the person feels relief. Keep in mind, you may not always hear the traditional popping or cracking sound. Nevertheless, the person may feel relief from the rocking/pressing on its own. While you're helping to crack someone's back, keep a dialogue going to make sure the person is comfortable. Ask if they feel okay throughout the procedure and instruct them to tell you to stop if they feel pain. If you keep trying to crack someone's back after they've expressed pain, this can cause injury.
Summary: Stick to gentle methods used by chiropractors. Have the person lie on a flat surface. Push on the person's back and buttocks. Pull the pelvic bones while pushing the back. Press on the back while raising and lowering the person's legs. Press on the lower back. Talk to the person throughout the procedure.

In one sentence, describe what the following article is about: Smiling more and incorporating laughter into your daily life has a positive impact on your overall well-being. Smiling and laughter is also contagious, so you may be able to influence the moods of those around you.   Smiling and laughing can also help to decrease stress. When you are smiling and laughing, your stress levels decrease, similar to the way that exercising causes your body to release feel-good chemicals called endorphins. When you consciously make an effort to smile and laugh daily, you may become more resilient to life's challenges. Being more resilient in difficult situations can help you to feel happy and be more successful. Perhaps the easiest way to cease frowning so much is to relax your forehead when you feel tension in your face.  You can even massage between your two eyebrows using your index and middle finger when you feel your brows furrowing. You may be frowning and furrowing your brows because you are having issues with your sight.  This may be forcing you to squint or frown.  If you have been having headaches lately, your vision is blurry, or your sight has changed, consider seeing an eye doctor.  They will be able to prescribe glasses, contacts or perhaps even Lasik surgery if necessary. If possible, keep a mirror on your desk at work to monitor your expression and correct it if you see yourself frowning.  If you are currently in school and there is a mirror in your classroom, try to situate yourself in sight of it.  When you are at home, sit near a mirror as well. Don't stare at yourself constantly.  Look occasionally to ensure that you are not frowning. Practice facial expressions in the mirror.  Practice smiling and then resting your face.  Repeat the process for a few minutes. Your family and friends can be particularly helpful in assisting you on your quest to stop frowning.  Communicate to them this wish and ask them to tell you when you are frowning.  Frowning may have become so natural to you that you do not even realize that you are doing it. Since you can't see your face unless you are in front of a mirror, as your friends to let you know when your face develops a scowl. You might say to them “Hey, I have noticed that people tell me I frown a lot, but I don't even notice I'm doing it.  Can you tell me when you see me frowning so I can learn to stop doing it?” When you are at home, and even while you are sleeping, you can train yourself to stop frowning.  Take a piece of clear plastic tape and place it between your eyebrows.  This will create a barrier on your skin to prevent you from frowning using your eyebrows.  You might be frowning during your sleep as well, so this will begin correcting the issue even when you are not awake. Try not to put the tape on any of your eyebrow hairs so that you don't cause irritation when you take the tape off. Though practicing facial expressions will assist you in your efforts to frown less, sometimes it is necessary to fake it until you make it.  Actively encourage and remind yourself to smile throughout your day.  Smile when you see someone walking past you. Smile when someone makes eye contact with you. On particularly sunny days, you may be forced to squint to protect your eyes from the harmful rays of the sun, which can cause you to frown.  However, consider wearing sunglasses to prevent yourself from furrowing your brow.
Summary:
Remind yourself that smiling and laughter is good for body and soul. Relax your forehead. Consider getting glasses. Keep a mirror on your desk. Enlist the help of others. Place tape on your forehead. Smile. Wear sunglasses when outside.
