[QUOTE="Lord Roco,  post: 15505, member: 395"]Are there any  boxers that are above 75 years and still active in the field?

From what I understand is that there are very high chances of brain concussion and related traumatic brain injury (TBI) rendering much of them unable to pursue such heavy motor activities in later life. Being a doctor, that too from a medical perspective, it would be interesting to know the names and research on the life and times of a few of them.[/QUOTE]
As of my last knowledge update in October 2021, it is quite rare for boxers over the age of 75 to remain active in the professional boxing arena due to the physical demands and health risks associated with the sport, particularly concerning brain injuries such as concussions or chronic traumatic encephalopathy (CTE). 

However, some notable boxers who have continued to be involved in the sport or have remained active physically in their later years include:

1. **Bernard Hopkins**: Retired at the age of 51, he had a lengthy and successful boxing career, becoming the oldest world champion in boxing history. Although he did not box professionally after 51, he is often cited in discussions about longevity in the sport.

2. **Foreman George**: While he officially retired from professional boxing, Foreman has remained active in various capacities, including commentary and business ventures, well into his 70s. He was the oldest heavyweight champion, reclaiming the title at 45.

3. **Riddick Bowe**: Although he has faced numerous health issues, including related to his time in the ring, he has occasionally shown interest in participating in exhibition matches.

4. **James "Buddy" McGirt**: While more of a trainer now, he has occasionally participated in exhibitions, although he is known primarily for his coaching rather than active boxing.

Research regarding older boxers often focuses on the long-term effects of boxing on brain health and the risks associated with continuing the sport into old age. Studies indicate that even with limited exposure, older boxers may still experience cognitive decline and a higher risk of neurological disorders. 

Many sports medicine specialists and neurologists advocate for stricter regulations and monitoring for older athletes to minimize risks while participating in physically demanding sports like boxing.
