The problem is that modern life is not geared toward moderation. The way our economy is structured, most people have to spend their entire day working in order to make ends meet. And for a lot of people "work" means being tied to a computer for 8 or more hours. The human body is really not well suited to doing any one thing for longer than 8 hours at a time, but unfortunately our lifestyle almost requires it.

It most certainly doesn't require it. I think most people are just resigned to it.
