Good to revive the Fitz nights yesterday, even if it was a Thursday. From what I can remember, the following topics needed follow up: Semi-identical twins; huge ligers (are they sterile?) and pizzly bears; mindfulness, meditation, depressive realists and forms of OCD; the tribulations of middle-managers; the share of London businesses that account for half of employment. What have I missed?
Also, something I meant to mention and didn't get around to - the German super baby. This is a kid with a gene mutation that makes him super-strong but otherwise healthy. You could view it as an interesting example of evolution at work - a random mutation produces a version of the species that would have been more likely to survive and pass on his genes (in cave man days at least, providing he doesn't need to eat twice as much food or anything).
