A lifetime, the gradual unfolding of bodily development, is actually a slow, lifelong explosion. After our reproductive prime, the body begins to fall apart. Then, when we die, this falling apart accelerates rapidly. With the advantage of time-elapse photography, we would see the body visibly exploding, its putrid froth seeping rapidly with the soil, air, and water that surrounds it.
But even now, in this moment, we are exploding; only in slow motion. But if we were able to see things as world-lines, a lifetime would look like a sausage “kerry” (the link between sausages)—a cloud of dispersed matter, followed by a short span of matter tightly packed, followed again by a cloud of dispersed matter again. And if we looked at the world-lines of the atoms that currently constitute us, we would again see lines from rain, to grass, to cow, to HEB, to fridge, and to mouth—that then swirl like eddies in our bodies for up to seven years, and then back out again. Our bodies contain their matter only temporarily. Which leaves you wondering where the notion of self-possession comes from.
