Incline the board about 15-20 degrees so that the feet are above the head. Optionally, put a damp cloth over the face to keep the water clinging to the face (Khmer Rouge technique), or put plastic wrap over the mouth but not the eyes or nose to prevent water from escaping the throat and sinuses (CIA technique).he water stays in the head, filling the throat, mouth, and sinuses with water. The lungs don't fill up with water so your prisoner doesn't asphyxiate, but they *do* feel their entire upper respiratory system from sinuses to trachea filled with water, simulating drowning.
What is a 'Median'. A median is the middle number in a sorted list of numbers. To determine the median value in a sequence of numbers, the numbers must first be arranged in value order from lowest to highest. If there is an odd amount of numbers, the median value is the number that is in the middle, with the same amount of numbers below and above.
In math, median is used to refer to the middle number in a group. To determine the median, you order the numbers from (lowest) to (highest) and find the middle number in the series. If there are two middle numbers, then add them together and divide by two to find the mean.
