my response would be, is it more "work" to do the physical or the mental/spiritual?
is the cog in the wheel where the real work is done or is the machine doing the work?
or at the bird's eye view, is it all the same work?
is exercising someone else's wlll any better/worse than exercising one's own?
i mean, on one level exercise is exercise.
comparing it to business, when running your own company you have to be the janitor all the way to ceo. definitely more energy is needed to run that senario. the returns also match that input(optimally speaking).
but is that system preferable to getting a 9-5?
