[ST:TNG] If Data has bio-functions, how can he be so easily disassembled? And how can he have an apparently indefinite shelf life?

Bio-functions are usually messy when their host-systems are disassembled and perishable when not actively participating in their native host.

Data doesn't really have any organic parts, if that's what you're thinking about. He's not a cyborg; he doesn't need to breathe, drink water, or ingest nutrients - aside from the occasional semiorganics-in-silicon-liquid-suspension to lubricate his insides. His skin again *looks* organic, but isn't. He is metal and plastic through and through. Any functions that resemble human ones are simulated.

Even if the "semiorganics" he ingests for lubrication were to decompose, there's no reason to think this would be a critical problem for him. His brother Lore was able to survive for several years drifting in the vacuum of space, for example.
