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.
Under relatively normal circumstances, we start struggling after a few minutes without oxygen. Without being able to convert energy and use it up, cells start to die. This happens throughout the entire body, but it is the brainâs lack of oxygen that is most urgent. âThe brain is a highly metabolically active organ,â Tishler said. âIt needs oxygen to generate the energy to function. Without the energy (without oxygen) it dies.â The brain normally takes up about 20 percent of the bodyâs oxygen. If it doesnât get what it needs, cells begin dying off, putting a person at risk of permanent brain damage. If a person suffocates, or suffers another type of involuntary oxygen deprivation, theyâll ultimately suffer brain death: the utter, irreversible loss of brain function. Itâs a pretty unavoidable succession of events.
