Q: If you're looking for a more challenging way to do an oblique sit up, lay down on a decline exercise bench. You should be able to lock your legs in by placing them over the top set of cylindrical pads and then putting your feet underneath the lower set. Complete your oblique sit ups just as you would on a flat exercise mat. Using the decline bench is more challenging because you will lift more of your body weight against the force of gravity. You can also add a little difficulty to your oblique sit ups by removing your hands from behind your ears. Either do this while keeping your feet flat on the floor and your knees bent like usual, or by holding your legs up in the air to also work on improving your balance and flexibility. Be very careful if you decide to do this, though, as not placing them behind your head means that your neck and head will be unsupported. If you want to do a more advanced oblique sit up, get the lightest weighted plate that you can find and hold it to your chest with both hands. Do your oblique sit up as you normally would, by contracting and twisting your torso. The added weight creates more resistance, making each sit up a little more challenging to complete. If using the lightest available plate weight is too easy for you, try using one that's slightly heavier. You can also do this by holding on to a medicine ball.
A: Do your sit-ups on a decline. Keep your hands by your sides or straight up in the air. Do a weighted sit up.

Q: Like CFLs, LED bulbs are low-heat and energy efficient. Unlike CFLs, though, they don't contain mercury, so they can be disposed of directly in the trash. If you have the option to recycle LED bulbs, though, that is often preferable since they contain many recyclable materials. LED bulbs as an environmentally friendly alternative. LED bulbs are easy to recycle in many places. Most countries don't have any national standard or program for recycling LEDs, but many local recycling centers are willing to take them. Call your local recycling center to see if they have a program for LED bulbs. Holiday lights are some of the easiest LEDs to recycle. Many areas have programs where you can even send bulbs in at no charge through the mail. Look online to see if there is a holiday bulb recycling option available in your area. Sites like HolidayLEDs.com are a good place to start checking for holiday light recycling in your area.
A: Throw away LED bulbs. Recycle Recycle holiday lights through the mail.

Q: Cardiac arrest is one of the most common reasons for a person to collapse and become unresponsive for no other obvious reason, such as due to a car accident. Providing CPR (if necessary) while waiting for the arrival of paramedics can double or even triple a person's chance of survival in the event of cardiac arrest. Find out if anyone in the immediate vicinity is CPR certified. If the person isn't breathing or has stopped breathing, then the first step is to check his airway. Place one hand on his forehead and the other underneath his jaw. With the forehead hand, slide his head backward and tilt his jaw with the other. Watch for any signs of his chest beginning to rise and fall. Place your ear over his mouth and feel for any breath on your face. If you can easily see something in his airway when you look into his mouth, then try to remove it, but only if the object is loose. If the object is clearly lodged, then do not try to remove it from his throat since you may inadvertently push the object farther down his airway. The reason we check the airway first is that if there is a blockage (or an obstruction, such as often happens in choking victims), and if we can easily remove it, our problem is solved. However, if there is not, check for a pulse and, if there is no pulse (or if you cannot find one and are in doubt), immediately begin chest compressions. Head-tilt chin-lifts should not be done on skull, spine, neck injuries. Instead, use the jaw-thrust method, in which you kneel above the person's head and place your hands on either side of his head. Place your middle and index finger along his jaw bone and gently push it upward so that the jaw is jutting forward, as though he has an underbite. Current CPR standards place the emphasis on chest compressions with a ratio of thirty compressions for every two rescue breaths. Begin chest compressions by: Placing the heel of your hand on the person's breastbone directly between his nipples Placing the heel of your opposite hand over the top of the first Positioning your body mass directly over your positioned hands Compressing hard and fast downward approximately two inches into his chest Allowing his chest to rise completely Repeating to a count of thirty At this point, add in the two rescue breaths if you are trained in CPR. If you are not, continue with compressions and ignore the breaths as they are much less important. You can stop performing CPR as soon as the person shows signs of breathing on his own. Watch for the rise and fall of the person's chest and place your ear near his mouth to check if he's breathing on his own. If the person continues to show no signs of consciousness or breathing on his own, then keep performing CPR at a rate of two rescue breaths to every thirty chest compressions until emergency responders arrive.
A:
Ask if anyone around knows CPR. Check the person's airway. Perform chest compressions. Check for signs of breathing again (reassess the person for breathing approximately every two minutes). Continue CPR until paramedics arrive.
