The more familiar the world becomes, the less information your brain writes down, and the more quickly time seems to pass.

We are made up of an entire parliament of pieces and parts and subsystems. Beyond a collection of local expert systems, we are collections of overlapping, ceaselessly reinvented mechanism, a group of competing factions. The conscious mind fabricates stories to explain the sometimes inexplicable dynamics of the subsystem inside brain. It can be disquieting to consider the extent to which all of our actions are driven by hardwired systems doing what they do best while we overlay stories about choices.

Our reality depends on what our biology is up to.

You are part of a complex social network that changes your biology with every interaction, and which your actions can change.
