I already had a reasonably good grasp of some parts of our culture as far back as I remember. I'm also already having trouble really keeping up with the world as it is now - I have trouble remembering that cell phones and laptops are commonplace, for example.

My model of how comprehension of culture works is based on the Critical Period Hypothesis - I suspect that we get one burst of really good ability to pick that kind of concept up, and then have a much lower ability for the rest of our lives.

It does occur to me that the kind of advanced science that would be able to reverse cryo preservation might well be able to recreate that kind of ability, though, now that I've thought enough about it to spell it out.
