Complete bollocks. Molecules don't age and everything in your body is molecules. If a molecule breaks down, in some cases the body has mechanisms to replace it with a shiny new one. Those mechanisms are themselves made of molecules. And if those mechanisms to stop working, in some cases those mechanisms can also be replaced. Nothing in fundamental physics makes aging inevitable.
From what I can tell, the reason why aging is so prevalent is that most species haven't had time to evolve the mechanisms that solve the problems that appear later in life. If there's some truth to this, you'd expect that the species that are better at this also tend to be the simpler ones, since for those simplicity also means smaller diversity of things going wrong.
