Today, we’re going to look at a fighter’s prime, and if a distinctive peak period can be ascertained by looking at a combination of age AND “career age” (time between debut date and fight date). In most professional sports, it’s usually agreed upon that a person’s prime is between their late 20s and early-mid 30s, with women having the potential of reaching this prime a few years later.
First, I took all of the fight outcomes where a fighter had a valid birth date and grouped my counts by age and career age.
For the record, a fighter’s first year is treated as year 0, just like a person’s age.
The Top 5 most common combinations are:
| Age | Career Age |
| 23 | 1 |
| 24 | 1 |
| 25 | 1 |
| 22 | 1 |
| 24 | 2 |
[#6 W125] 
[#5 FW] 
[#16 FW] 
[#6 HW]
