I do multiple 12/13 hour flights per year. It's not a big deal once you get used to it. The hardest part is just preparing yourself to be able to shut down properly. We spend too much time constantly stimulated that sitting still for a while freaks people out.

I find there is a benefit to being alone with your thoughts for half a day or so, in a physically inactive state. How many people honestly ever spend that time 'switched off'.

It's all in how you approach it really, glass half full/empty
