In one sentence, describe what the following article is about: Immediately ask someone to call 911 (or another emergency number) as you begin providing assistance to the unconscious person. If you are alone, shout for help as you begin the Heimlich maneuver. Move the person onto her back while supporting the head and neck. Place the choking person on a hard surface (such as a floor) that can support the body while you perform the maneuver. Using your thumb and an index finger, open the choking person’s mouth. Position your thumb on top of the person's tongue and your other finger under the chin. If you can see an object and it is loose, remove it from the person’s mouth. With the person's head turned to the side, use a finger or two to gently sweep the object out of the person’s mouth. Be careful not to push the object deeper. If you cannot see what is lodged in the person’s mouth, tilt the head back and lift the chin. This will open the person’s airway. Generally choking victims will not also have spinal injuries, but if the person has suspected head, neck, or spine injuries, use a jaw-thrust to open his airway, not head-tilt chin-lift. Lean your head down and place your ear near the unconscious person’s mouth. Listen for sounds of breathing. Watch the person’s chest to see if it rises and falls, indicating that the person is breathing. You can also place your hand on the person’s chest to feel if it rises and falls. Listen, watch, and feel for breathing for five seconds. If the person is not breathing, start performing rescue breathing. While waiting for emergency medical assistance to arrive, keep careful watch over the person and perform first aid as needed:  Make sure that the person continues to breathe. Check the person’s pulse frequently. If the person’s breathing or pulse stops at any time, perform CPR. If the person’s back is not injured, roll the person on her side. Bend her top leg at the knee. Keep the person warm while you wait for assistance.
Summary: Seek medical assistance. Roll the person on her back on a hard surface. Open the person’s mouth. Look into the victim's mouth. Tilt the head back if you cannot see an object. Watch for evidence of breathing. Give first aid for unconsciousness if the person is breathing.

In one sentence, describe what the following article is about: When filing your nails from the side to the center, you should always hold the nail file perpendicular to the tip of the nail. This will prevent weakening the nail while filing.  Filing at an angle from above can cause the nails to thin. If your nails are already thin, hold the nail file flat to your nail, tilting it to file from slightly underneath your nail.
Summary: Hold the file flat against the nail tip.

In one sentence, describe what the following article is about: High intensity interval training (HIIT) switches between bursts of intense activity and brief periods of less-intense activity. HIIT burns a high amount of calories in a short time and continues to burn calories after the workout.  A good twenty minute HIIT program is to do forty-five seconds of each the following exercises: push-ups, squats, butt kicks, tricep dips, and lunges. After one round, rest for 15 seconds, and repeat. Do three rounds total.  A good HIIT program can help you lose belly fat, which will help reduce your love handles. A fun exercise that really tones up that troublesome love handle area is using a hula hoop, sold at most fitness stores. Put on some music and swivel your hips, maneuvering the hoop higher and lower up and down the column of your waist area. After a while you can really feel your oblique muscles kicking in, meaning that you are starting to have some effect on strengthening the muscles below the love handles area. Decline twisting sit-ups are more intense than normal sit-ups, as you are working against gravity as you lower the body and rise up again. Just perform a set of normal sit-ups, but twist to alternate sides as you rise from the floor and reverse the position as you lower back to the start position.  Lie on your back with your knees bent and your feet firmly set on the ground. Raise your torso, focusing on twisting as far to one side as you possibly can. Lower back to the floor slowly, as this helps work the muscles across the full range of motion.
Summary:
Do high-intensity interval training. Use a  hula hoop. Try decline twisting sit-ups.
