Look at them running.
Look at young teens running. The effortlessness with which the body yields to their kinetic wishes. The ground doesn't claim them yet. They spring away from it. The air around cleaved apart in nano seconds. The body, a vagabond traveler through space. Look at the old running. The wish and the body, out of sync. The ground waiting to claim them. Soon, it will have them. So every step feels progressively heavier. Body bent down in respite, yielding to the siren songs of ground. Air feeling heavy. gasping for it. The body solidifying in the space, decomposing into a being of here and forever.
