Haha, that was not a refreshment for me at all, but something I did not know at all. I haven't even touched kanji yet, because I want to make sure I have all of the kana memorized first (I've got hiragana down, but katakana...not so much).

However, I understand what you're saying.

So...does that mean 「知」 alone has something to do with 'to know' or 'to understand'? 'Chi' means 'blood' though, right? Is that a different kanji?
