How old do you have to be to have a FIS?
Excuse me, but could you clarify something for me? The paragraph mentions 'FIS' and mentions the requirement of an age limit. Could you please elaborate on what exactly 'FIS' stands for, and specifically, what is the minimum age one needs to be in order to have or obtain one? Is this an age limit that's universally applied across different countries, or does it vary depending on local regulations? I'm genuinely curious to understand the specifics behind this requirement.
