0 - 100 years in Senegal (Wolof language)
Wolof is the most widely spoken language in Senegal, spoken natively by the Wolof people (40% of the population) but also by most other Senegalese as a second language.
Wolof is a language spoken in Senegal, Gambia and Mauritania.
French is also spoken by most people in Senegal (and in many other parts of Africa) and I made a video in French as well.
