Burnout is more of a mental phenomenon than a physical one, perhaps it stands to reason that with thought work you burn out mentally much quicker. I think in general humans have a much lower capacity for thought output than they do physical output. With exceptions of course. Another issue I believe is that there is no shameless lulls in thought work, at least for me personally it is 100% all day. Whereas in all the physical jobs I've done you have to wait for things to happen, people to do things, stuff to get unloaded etc. Not true of all physical jobs of course. But there can be a lot of idle time that you don't feel guilty for.
