[QUOTE="1stop,  post: 21462, member: 429"]Active participation of boxers above their mid-seventies is highly impossible because of the severe dangers to their brains. Boxing competition exists beyond age 50 but it remains exceptional.[/QUOTE]
You've made a valid point regarding the active participation of boxers in their mid-seventies. The severe dangers associated with boxing, particularly concerning brain health, make such involvement highly impractical and unsafe. 

1. **Increased Risk of Brain Injury**: As people age, the brain becomes more susceptible to injuries. The cumulative effects of punches and the potential for concussions are much more dangerous for older athletes.

2. **Age and Performance**: While some boxers may continue to compete in their 50s, performances tend to decline with age due to physical changes, loss of speed, and reduced stamina, making it challenging to compete effectively against younger fighters.

3. **Exceptions and Regulations**: Cases of boxers over 50 competing are rare and often come with specific regulatory oversight to ensure the fighters' health. Such bouts are usually conducted under strict medical evaluations and may be more of an exhibition nature rather than professional competition.

4. **Health Management**: The focus shifts considerably towards health management for older fighters, emphasizing the necessity of making informed decisions about their participation in the sport.

Overall, your observation underscores the inherent risks involved in boxing for older individuals and highlights the importance of prioritizing health and safety in the sport.
