I just got back from China yesterday after a three week vacation. The return trip took me over 20 hours door-to-door! To get from my dad's flat in Suzhou to my flat in Auckland, I took a taxi, a train, a subway, a maglev(!), a three hour flight, an 11 hour flight, then a bus, all without any sleep! So I was exhausted when I got back, and slept for 12 hours, being awoken by my alarm clock for work.
