In those cases, the spread between the bid & ask goes to the market maker as compensation for making a market in a stock. For a liquid stock that is easy for the market maker to turn around and buy/sell to somebody else, the spread is small (narrow).
In cerebral hypoxia, sometimes only the oxygen supply is interrupted. Brain cells are extremely sensitive to a lack of oxygen. Some brain cells start dying less than 5 minutes after their oxygen supply disappears. As a result, brain hypoxia can rapidly cause severe brain damage or death.
The chart below shows how long you can be exposed to certain temperatures before it will result in frost bite. For example, a temperature of 0Â°F and a wind speed of 15 mph creates a wind chill temperature of -19Â°F.Under these conditions frost bite can occur in just 30 minutes.actors like body fat, age, alcohol consumption, and especially wetness can affect how long hypothermia takes to strike. If you fall into water, the situation becomes drastically more dangerous. For example, in water 32.5 degrees Fahrenheit or colder, you might not survive more than 15-to-45 minutes.
