A lot of people feel this way, but the reality is that we already do almost everything without conscious control, we just don’t tend to notice.
Not to mention the majority of the systems in our body are also beyond conscious control, and for many, beyond awareness completely (e.g. the nervous system).
The book “Flow” is a really interesting read, and describes how one’s approach to daily life can lead to something closer to that athlete’s state.
This is closer than most people realize.
