I've read that older people should do crossword puzzles in order to keep their minds sharp and fend off Alzheimer's. I've decided that when it comes for me to make sure my brain doesn't go to mush, I'm going to plan out routes using the Seoul Metro system. Seriously, I'm becoming Lord of the Buses here.

I had to go to the immigration office today to pick up my alien registration card (Side note: I feel like I'm betraying my Mexican heritage by becoming a LEGAL alien but...what can you do?) and I managed to get from Omokyo to Dangsan using nothing but my wits. For those of you who are familiar with my woeful sense of direction, you'll appreciate that this is damn near a Christmukkah miracle.
