This is a work of genius, and a brilliant way to illustrate the idea of the ‘lifespan’.
It would make a fabulous subject for analysis by physiotherapy students, and a great way to think about the idea of embodiment.
For some reason, it reminded me of a quote by Maurice Merleau-Ponty:
The world and Being hold together only in movement; it is only in this way that all things can be together. Philosophy is a reminding of this being.
