As cool as Arnold is in the first Terminator, i totally agreeSci-FI it is what it is. If Skynet was able to construct an infiltrator unit to mimic a human with bad breath BO etc it's not difficult to imagine Skynet making the T-800 with a human like skin that was also developed to artificially age for possible long term infiltration.
Food for thought, remember in T1 the Terminator started to rot and smell bad and that skin was beging to decay kinda like aging dying.
