imagine yourself in a deep bit with cold sandy walls .. you try and pull yourself out ..

you know you will starve or die of thirst if you don't get out soon.

The more you try to pull yourself out .. the more the sand comes down on you ...

that's is what depression is like

Results of an NIH study of Seau's brain revealed abnormalities consistent with chronic traumatic encephalopathy (CTE).

''The brain was independently evaluated by multiple experts, in a blind fashion,'' said Dr. Russell Lonser, who oversaw the study. ''We had the opportunity to get multiple experts involved in a way they wouldn't be able to directly identify his tissue even if they knew he was one of the individuals studied.''
