We had a discussion about the long term effects of collisions and impacts in football. (CTE, Alzheimer's, Parkinson's, Dementia, Depression, etc) Research is being done on a collar that would compress the jugulars (about like a necktie in terms of tightness) and allow a little less blood to return to the heart. The extra blood in the brain would act as an internal cushion and not allow the brain to slosh around so much theoretically reducing the impact of long-term collisions. Woodpeckers and Rams are examples in nature where we see repetitive collisions without negative consequences. A woodpecker actually uses its long tongue to wrap around the backside and protect the brain.
There is still a lot of research that needs to be conducted to see if this or some other solution can be used to prevent the damaging long-term effects of impact. One of the major obstacles that needs to be overcome in regards to CTE is it can only be diagnosed post mortem currently. Here is the link to a small story that shows what I'm talking about:
