If life is simply a sustained series of networked chemical reactions and aging is the slow degredation of that network then it would seem prudent to study complex networks and their degredation when repair mechanisms are removed or failed.

Can anyone think of some complex non-biological networks? e.g. the Electrical grid, water systems, internet, gravitational fields, MySpace :)

I think I'm going mad thinking about this stuff. [:o]

I dont understand your problem, why are you getting mad?.
Offcourse it is possible to make simulations of biological systems it is used to be called "systems biology".
I have done such simulation as you describe myself. The biggest problem for this kind of simulations as I see it is the lack of quantitative biological parameters.

The madness is stemming from the complexity of the challenge. Trying to visualize and model all of the inter-related concepts of simulating a biological network in my mind. I've been jumping all over the place studying and reading white papers, books, journals, thesises, etc on microbiology, informatics, MD, genetics, pathways, chemiformatics, modeling, threading, game theory, genetic algorithms, complexity theory, baysian networks, chaos theory, design patterns, gerontology, agent based programming, GROMACs, E-Cell, RDBMSs, MMRPGs, protein folding, distributed computing, super-computing, blah, blah, blah. I've been turning this all over and over in my head and attempting to view it from many angles to see if a clear path will iluminate itself. I start putting it on paper, whiteboards and in graph paper and i just keep sketching out models and meta-models but none of them feel right. Grrr. I had to take a couple of weeks off to clear my head b/c I was going bonkers.

The biggest problem for this kind of simulations as I see it is the lack of quantitative biological parameters.


True. The combinatorial explosion that occurs when you overlay the various models upon one another are staggering but it has to be done. Dismissing it as intractable = death for us all.
