I found the parts labeled 'Science Fiction' to be particularly entertaining. A typical remark: "Nanorobots ñ the biocomplexity of putting a nanorobot in the body to enter and repair cells has been massively overestimated [sic]. ëWeíll never know enough to go in and cure a cellí. This scenario also fails to recognise that the emphasis in health care is on developing non-invasive techniques and essentially persuading the body to heal itself." Sure."
