All you've done here is restate "there are children starving in Africa, so you are not hungry." It's even got a dash of "I'm from Wisconsin, you call this cold?!"

I don't think anybody is arguing that we engineers are not better off than starving children in Africa or soldiers who are forced to potentially suffer permanent harm from bad sleep culture[1], it's just being pointed out that due to the nature of the job, there's usually no reason to come in early, and there are reasons to come in late (health reasons)

A lot of software engineers grew up working late and it's hard to break that habit or it just doesn't feel natural. I have no problems with waking up at 6:30 to make it into the office but if I had the choice I would pick 11 because it fits with my natural preferred schedule I've spent most of my life living.

Unless you have a legitimate medical issue it only takes a few weeks to reset your schedule.
