I found a new growth today, bring the total to 13 that I can confirm (and a few that I suspect). Fortunately, it's only small, sitting on the inside of my right wrist, and it doesn't seem to interfere with the bones or the tissue around it. Due to its size and lack of affect on me, it's likely not a recent growth, and I just haven't noticed until now. Nothing to worry about.
Kana
I have comitted all the hiragana to memory, including the sound changes and combinations! Now only the somewhat more difficult katakana to remember and hundreds of kanji!
Shit.
