I spilled water on my keyboard. I can still use it although it sustained some damage.
This made me think about the difference between live and still matter. In contrast to still matter, live matter can react and re-organize in response to damages. My body matter does it both on the unconscious and involuntary level (healing of wounds, to give one example), and on the conscious level (learning how to fall while minimizing impact).
The mortality of all living things refers to the duration of time in which the ability of matter to reorganize lasts. In this sense, my body creates and constantly recreates time and space. My body creates time as it reverses the damage and returns to an earlier point. My body creates space as it expands and contracts (e.g. losing or gaining weight), or when it reworks its lining – the skin – that closes itself once perforated.
The first and essential forms of space and time are therefore dependent upon bodily actions of self-preservation.
