Regarding princessfrodo's comment on the book, yes, there are cyborgs, and the book was written by Philip K Dick...
Actually, as been mentioned earlier, there -WAS- a book he wrote called 'Do Androids Dream of Electric Sheep,' and the Blade Runner movie was based off that book.
But there was a DIFFERENT SF story in a DIFFERENT book which was called
Blade Runner, written by Alan E Nourse. I had recently stumbled across that one and it was quite a thriller of a story:
The Baby-boomers had overtaxed public health system cuz they (will) all retire at once, and to the government says no one can get healthcare unless they also submit to sterilization.
Many doctors with other ethics objected, quit, and found other jobs. Some of them, though, joined up with the city's youth gangs, and they would do illegal operations in secret hideaways or in people's homes - provided they could get the supplies. A 'blade runner' in THAT story was a kid who could break into a government hospital, defeat alarms, steal what was needed, and bring it to the underground doctor. Stuff like kitchen-table appendectomies.
Next, the street-doctors notice that some new kind of epidemic is breaking out and the government hospitals are ignoring the problem... (no more spoilers!)
Anyways, I went into the 'Blade Runner' movie with the hopes of a good medical + 'jewel robbery' type of thriller movie, and I got .... Sting. (aka Gordon Matthew Thomas Sumner.) What a disappointment!
