Fusing Thoughts On Diffusion

Diffusion. This lil bugger of a word has been hanging around in my head for a lot of the better half of the day. There is a gut feeling that pushes me to write.
I come to gather that the characteristics of a human being is kind of like a huge fusion process. It starts off with a core and along the way powerful and impact making words or circumstance will generate enough energy to permanently fuse itself with the core of a being generating a compound.
Having said that, I have this muse. Character and personality is volatile. It is just waiting for enough impact of a circumstance to start the whole fusion process. Food for thought isn't it? No matter how dormant the nature of a particular human being that has not changed in years, it is just the lack of the things around that shapes? And when it happens, which it happens to everyone, why should anyone be surprised at all?
I relate even further. Often, newly fused compunds have a lot of new energy. Again, how true is this? Whether the energy comes as endothermic (active absorbance) or extrathermic (active release) it reflects. Either someone becomes highly energetic to preach their new ideals or become recluse and starts absorbing the world around.
But think of those events, circumstance, words and stuff that fleets on without fusion. It never shapes or moulds a person. We just let them pass on by, like an insignificant spec of particle in this whole process. Just how much residue is left from all these fleeting particles? Food for thought isn't it? Just wonder where all the pockets of residue went?
Diffusion, works pretty much the same way. Just probably more painful. Something drastic happens and strips part of the element in the compound of our character away, revealing a new old mix probably with residue of the former compound. And diffusion also happens to generate a heck load of energy. (Think Hiroshima) Whether to channel such energy positively or to let it all meltdown like Chernobyl, is pretty much choice.
Rant and musings aside, I would probably want to remember, that we are all born with a core. Its just sad sometimes, through all fusion and diffusion, that this core, will never be the same again.
