Is it possible to imagine that one day soon it may be possible to carry out medical tests without having to extract blood from the body? What I have in mind is being able to shine a light through, say, that piece of skin between stretched thumb & forefinger & by the magic of some kind of spectroscopy (not, I suppose atomic absorption) find out all you need to know?
It ought to be – sticking needles in people is very primitive.
