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 brain can survive without oxygen for about 3 minutes before it is permanently damaged. After 3 minutes there is likely to be severe brain damge which usually leads to a coâ¦ma. If you survive the coma you will probably have very limited brain function i.e. not being able to walk or talk.
