From Christopher Young, Sheffield, UK
In media coverage on the topic of significantly extending human lifespans, there seems to be a general view that doing so would be an unalloyed good. But the most significant impact would be an increase in population. If we all lived an average of 12 per cent longer than at present, that would amount to another billion people, disproportionately older. I don’t see how this would be a good thing (2 December, p 9).
