I’ve been reading a lot recently about the new book from Barbara Ehrenreich, Smile Or Die: How Positive Thinking Fooled America And The World, and it looks fascinating. I first have to admit to not reading it yet – it's published in the UK at the end of the week and on pre-order. But the extracts I’ve read have been interesting, disturbing and depressing in equal measure. I’ll do my first book review as soon as I’ve got through it. But here are a couple of my initial thoughts about some of the issues Ehrenreich raises.

I have written before about my disdain for a lot of the pop psychology reported in the press *cough Oliver James*. I am sure that this does not represent a lot of the real research that goes on within the discipline but there does seem to be some fundamental problems within psychology that a few academics are finally shining a light on.

These fundamental problems include the lack of empiricism within the discipline (OK, fancy way of saying you're making it up) which then feeds into implicit universal assumptions about human behaviour.

There’s a very illuminating leader in The Lancet last week about maternal mortality and the fact that despite sustained global campaigning efforts there has been little progress on the Millennium Development Goal to reduce maternal deaths by 75% by 2015.

A while ago I wrote a post at Vagina Dentata about periods. I was sick of menstruation being a hidden and taboo issue and one that we as a Western society fail to talk about. That post got the biggest response I have had both in terms of comments on the blog and in person from women and men alike.

This response included a great post from Arikia (The Millikan Daily) about tampon scarcity in Brooklyn – yep land of the free, with not a red mouse between them.

I guess it is something that they are still inventing things that surprise you. You think you have everything you ever wanted, every consumer good imaginable and then something pops up and you are left open-mouthed.

This is how I felt recently when I came across (no pun intended) vagina fresheners. Yes, I’m afraid you read that right. Mints that feed into the Va-jay-jay to give it a tangy flavour.

It is distasteful to see a number of anti-vax headlines (which have subsequently been taken down) reporting the tragic death of a 15 year-old girl after she had received the cervical cancer jab. Of course we learnt soon after that Natalie Morton had a malignant chest tumour but that was after the vaccination programme had taken a hit.

None of this furore really leads to a conducive atmosphere in which we can talk about possibly extending the vaccination to boys, but I’ll give it a go.

I'm very excited to be guest blogging at The Lay Scientist and have to say its a bit like being in someone else's flat without them being there. I obviously don't do that too often and am just managing to keep myself out of Martin's knicker drawer.

I thought I might start as I mean to go on, by writing about vaginal orgasms. Call me an attention seeker.

I was sent a study from the Journal of Sexual Medicine by the fabulous and recommended Dr Petra Boynton and have to say that, however angry it made me, I will be forever in debt to Prof Stuart Brody for introducing the word 'clitoromania' into my life.
