This video always makes me laugh. This is a part from early Indiana Jones series. Although some scientists say that there is a limit of learning languages, others claim that one can learn as long as he/she tries hard. I agree with the former claim because I have met many people so far who said “I know 5-6-7-8 languages”. When you want them to speak fluently, they just stop there. When we say “speaking a language”, we mean the communication without any problem. I can say “I know English, but it is nor perfect”. I think many of you agree with me because we still hesitate using some certain phrases or verbs in English. I can write, read and understand French, but I can only talk about daily matters. This does not mean that I know French. Similarly I can write, read and understand Spanish; however, I can’t go beyond saying “Hello, how are you, how old are you?” etc. I do not say people can only speak 2 or 3 languages fluently but I think there is certain limit with regard to the potential of our brains.
