The work is do-able but it is very stressful if you love staying active, long hours and lots of physical walking 6-7 days a week, read that again there is no work life balance if you are okay with not having a life this is the job for you!!
The job is different for everyone it all depends on how bad you want things. I love working and this is a great job for hard working people like me. You go to work and do your job you should have no problems.
