There's no chip on my shoulder; you won't catch me moaning about it and I hate it when folk try to belittle other degrees or anything like that. It's just blatantly obvious though, don't know why some other's have a problem with it.
I'm sure most would happily confirm that medics have to work harder than them, why then do they have a problem engineers working harder than them? Maybe it's simply due to an image problem surrounding engineering in general.
