He might be a knockout artist and an exciting brawler in the Octagon, but that does not mean that UFC middleweight contender Paulo Costa does not worry about the brain damage that comes with being a professional MMA fighter.
At 28 years of age, ‘Borrachinha’ is actually very concerned about what condition he wil be in once he hangs up his gloves, which he intends to do in just about eight years, hoping he will have fulfilled all his goals in the Octagon by then.
In an interview with Ag Fight, Costa explains how brain damage symptoms tend to become worse with age, so he expects to call it a career by the time he is 36, and then, after he is dead, donate his brain for research in order to tackle the problem in the future.
