All the traveling is catching up to me a bit...
Feeling tired today...

Did a quick calculation while sitting through a way ran-over meeting this morning:
Time spend flying to Seoul and back to US: 26 hours
Time spent on to/from and waiting in airports: 11 hours
Time spend in Seoul: 41 hours

well, that's almost 1 hour in Seoul for every 1 hour spent in traveling! Not bad! :-)
