I think you've outlined something really important here in terms of value and individualism. Some people get value from spending time in the great outdoors, others by growing and caring for a family, for a large number of people (I imagine) in Silicon Valley there is no better way to spend your time then sweating at 1 am because you need to solve a problem. I'm one such person. Fortunately I don't have a family to look after, so I can dedicate myself to doing exactly what I absolutely love: working. That doesn't mean I don't try to get enough sleep, that I don't exercise daily, and occasionally participate in yoga (not to mention my daily morning meditation practice). But still, to me, this type of lifestyle is fun. We'll see how old age influences my perception, of course.
