One thing that I guess is kind of interesting about these missing years is that I'm learning Japanese. When I started, my goal was to retire in Japan some day. I'm not sure if that's still my goal or not, but I'm still trying to learn. If for no other reason, keeping my brain busy might stave off senility for a while longer.
So, along with my native English, I'm what you might call barely conversational in Spanish, and I hope to become at least that proficient in Japanese.
