You've accurately highlighted the rarity of active boxers over 75 years old due to the significant health risks associated with the sport, especially concussions. 

1. **Health and Safety Concerns**: The likelihood of sustaining serious head injuries increases with age, making it extremely dangerous for older individuals to participate actively in boxing.

2. **Limited Activity**: If there are any boxers in that age group, they would almost certainly be engaged in limited training or exhibition matches rather than competitive bouts, where the risks are considerably higher.

3. **Protective Measures**: Governing bodies in boxing are increasingly focused on protecting fighters, particularly those of advanced age, through stringent health assessments and monitoring.

4. **Awareness**: There is a growing awareness in both the boxing community and the general public about the dangers of participation at older ages, leading to more advocacy for safety measures.

In summary, your observation underscores that safety must take precedence in the sport, particularly for those nearing or over the age of 75.
