What are the intellectually MOST rigorous jobs?

[rootX]

I don't think there's any job more mentally demanding than being a professor working towards tenure who has to juggle teaching college courses with writing grant proposals and doing state of the art research in a real field of science to publish in peer reviewed journals.

@general:
This thread is nonsense.
1) It is not possible to compare different jobs in different fields
2) It is not possible to come up with a criteria to find if a particular job is mentally demanding (other than providing opinions) because it largely depends on who is doing the job
