thanks for the answer NightIP. the TPE-NGO-ICN-TPE flights, do you mind giving specifics? How long is each flight, how long you sit between flights and what is the longest duty day you have had? Do you usually show up at the same time every night for these flights? I suppose if you get your body used to doing the night flying at approximately the same time, you can adjust to that. I was told it's when it changes on you every day where it could wear you out.

Are there also similar flying here in the US out of CVG? And if so, where is the flying to?

The other day I saw a 767 freighter flying out of IAH during the day, and there is always 767 passenger airplanes parked by the Fed Ex hangar in IAH. where these usually fly to?
