The average annual salary for head coaches at major colleges (not including four schools that moved up to the Football Bowl Subdivision this season) is $1.64 million, up nearly 12% over last season â and more than 70% since 2006, when USA TODAY Sports began tracking coaches' compensation.
A stroke occurs if the flow of oxygen-rich blood to a portion of the brain is blocked. Without oxygen, brain cells start to die after a few minutes. Sudden bleeding in the brain also can cause a stroke if it damages brain cells.
The decrease of oxygen to at least one body part is known as hypoxia. The total lack of oxygen is known as anoxia. Brain cells are destroyed after 4 to 6 minutes without oxygen. When the flow of oxygen to the brain is completely cut off, a person will lose consciousness within 10 seconds. Extended hypoxia leads to brain damage and ultimately death.
