Honestly I do not believe that a translation always loses the feeling of the original at all, it heavily depends on the context, your approach and how well you know the target language. Ofc, if you were to translate an idiom to a regular sentence (ex. in Swedish "Du har fått det om bakfoten" - "You're wrong"), yeah, more often than not the feeling will get lost there bc the eccense differs greatly between "You're wrong", and "You are mistaken".

Ni, ni - Neither, nor

Yes and no, it really depends on how often I use the languages I know. But there have been often times recently where my language abilities got rusty bc of me being upset and sad, bc of the feeling of discouragement. But eventually no matter what, you've got to pick yourself back up.

Hi, well that depends on what you define as "perfect memory". If you define it as remembering certain things quick enough for you to grasp them one after the other, then yeah I would say a large chunk of humans possess that, however if you were to define " perfect memory" as remembering everything quickly all the time, well from what I have seen most humans do not seem to possess that. But then again it does also depend on your daily routine. I hope my reply makes sense.
