Every `.` in this text is a digit and every sentence is correct :

> 
> Captain was born in `. . . .`  
> 
>  He will be `. .` years old, a canonical age, in `. . . .`  
> 
>  In this text, There is only `.` different digits, each of them being used `.` times
> 
> 
> 

**Can you find the canonical age?**

**EDIT**: "canonical" age here means "advanced" age. Sorry for that, wasn't aware this meaning was absent in english language!

**NOTE**: This was written in **1999**
