Wow! Today's run was -2F and it was sheer delight. To feel the snow crunch under my foot trough my extra layer of skin (primal mocs) while being toasty warm with only a thin wool business type sock on was amazing. Some barefoot purists out there may say you'd get more feel of the experience with nothing on you're feet. Possibly. For the first two minutes. Grin.
-- Every 22 seconds, someone in America receives a brain injury.
-- That totals 1.4 million people in America receiving a brain injury every year.
-- Of these, 50,000 die; 235,000 are hospitalized, and 1.1 million are treated and released from an emergency department. (stats are only known for those who seek help in an ER) (BIAUSA.org)
-- The annual incidence of TBI alone is higher (perhaps up to 6x) than that of breast cancer, multiple sclerosis, spinal cord injury and HIV/AIDS combined. (Reference)
-- Every brain injury causes permanent damage, even mild concussions. The good news: the brain is resilient, and often creates new pathways, making it seem like no permanent damage occurred. The bad news: neurological "detours" use more brain energy and people can experience the world as "being harder" without realizing why.
-- Having one concussion increases the chances of having another. This snow-ball effect continues to increase with each concussion.
-- Damage from subsequent concussions is cumulative -- so multiple mild concussions can result in significant impairment, even if the first 6 or 7 did not seem to effect you.
-- Brain injury is often called the "Silent Epidemic" because brain injured people often look "normal" despite experiencing life-altering effects.
