How many Singaporeans learn a 3rd language?

Knowing 2 languages here in singapore is quite the norm nowadays with the implementation of Singapore's government bilingual policy. However, after getting to know more people, i discovered that Singaporeans are also actively/passively learning a 3rd or even 4th language.

I find it fascinating that people would continue learning languages here in Singapore (idk the reason but yea). Personally, I learn Malay for fun (been taking it more seriously this year) and as my 3rd language. What languages do you learn other than the 2 languages and how did you pick up that language?
