Research shows that age is not correlated with fertility…um OK

I’m back on my data hunt for my course project to develop a web app…and I came across a research paper that explored factors associated with fertility in a small district in India*.  The abstract of the paper begins with:

“This paper focuses on the cause and effect relations on human fertility. Here fertility is used as the number of children ever born for a woman….”

Alarm bells rang as soon as I see ’cause and effect….’.  But I was intrigued, so I read on.  The factors that this study looked at were ‘natural factors’ (including age of woman, age of woman at marriage, religion and type of family) ‘economic factors’ (including employment of woman and spouse, income of woman and spouse) and ‘knowledge factors’ (including education of woman and spouse).  I should now mention that this is clearly NOT a piece of medical research, rather came from a journal of anthropology.  Studies that look at non-medical factors can be revealing never-the-less, so here we go…
I loved the result that the more educated a woman and her spouse were the fertility rate lowered.  Basically you can possibly turn this around and say that the less educated you were the more likely you were to have children.  I think we can guess why.  But it is the way that the report concludes which makes it sound rather amusing…
“Conclusion: Higher employment, higher income of both husband and wife and nuclear family system could bring the reduction in the fertility level of the women in Kanyakumari district”

CORRELATION DOES NOT EQUAL CAUSATION – BAHHHHHH

I know that this research paper was probably trying to assess what causes the high birth rate in this particular district, but I think the translation and the way the conclusions have been made make this a paper a funny read if you are into that kind of geekery.  So Ladies – lose the jobs, dumb up your brain cells and knock a few out of your husband too, and don’t worry, age is not correlated with fertility, that is if we want to learn some lessons from Kanyakumari district!

Oh yes and here is another one of my favourite xkcds.

Cancer Causes Cell Phones – Duh!

Wonky Boobs – a side effect?

If I could post a picture of my wonky boob I would, but I don’t think the internet needs anymore pictures of wonky boobs, I’m guessing it’s a pretty saturated market out there.

Yesterday I woke up and looked in the mirror to discover my right boob had grown overnight, it also felt overly soft compared to normal.  Chris thought I was exaggerating.  So I didn’t think much else of it.  But this morning it was still like that, so rather than poo pooing my crazy claim, Chris examined it a bit closer.  Upon closer inspection, he concurred that my right boob had indeed grown in size, whilst also laughing in amazement when he came to this conclusion.  Luckily I shared his humour on this one.  I am guessing this is a side effect of the Letrozole (well I can’t think of any other explanation for it!).  I am due to ovulate from the right side, so is it coincidence that it was my right boob that grew?

Will my boob return to normal size and match the other one??? I hope so!  Or perhaps next cycle the other one will catch up – may be I won’t need a boob job after all!  (Just kidding, I don’t really want a boob job, and never have, luckily I like my boobs as they are).dani
