Never said that you would, unless you were a newborn trying to catch up to a 5 y/o

It's not like you have to re-learn all concepts from scratch like a newborn. Concepts are harder to learn than language.
For example kids take years to learn how to count numbers. It's not because learnnig 10 number words is hard at all; it's just that it takes them a long time to learn the concept and usefullness of counters.
On the other hand, an adult can learn to count in Japanese in a day. But they probably need lots of practice to get used to the concept of breaking down numbers into 10000s. An adult can also quickly learn to count in Hexadecimal, but learning to do Hex arithmetic quickly would take much longer.
Here's what I think:
- Drop a newborn in a different country - and he's already fluent in any language, for his age, ie. zero

.
- 1 y/o in a different country - speaks nothing - still normal for his age.
- 2 y/o in a different country - maybe lagging behind by a few words but within a few months he can be fluent for his age.
- 10 y/o in a different country - lagging behind by about 2 years (I did that).
And so on. The older the person the longer it would take to catch up to native level for his/her age, but it's not like it would take 5 years to reach the level of a 5 y/o.
