This was the route that I was taking to Taipei this time: Berlin, Paris, Bangalore, Delhi, Taipei... with 7 hours in Bangalore and 4 hours in Delhi, resulting in a total travel time of about 38 hours.
Everything went surprisingly well and I did a lot of work. However, my day/night rhythm is basically completely gone by now. Need to try to synchronize with local time.
Oh, and if you're asking yourself "why"? Because airline ticket pricing is the most ridiculous thing on this planet, even worse than stock exchange. Any more 'direct' asymmetric Germany->Taiwan->India->Germany flight would have been about three times as expensive as both a Germany->India->Germany and a India->Taiwan->India round trip ticket together.
