I think we've moved to thinking of parenting and pregnancy as something in which you should lose yourself.

I think women - relative to men - tend to feel that they have to do the household chores on top of everything else. This becomes even worse once you have kids. It's enough to have a full time job; a full time job plus a family is even more.

I had always been told that you shouldn't clean the litter box when you're pregnant, because of your cat. And I think that is overblown - unless you have, like, three kittens in your house that are living outside and eating raw meat, this shouldn't really be a significant source of concern.

For many women - myself included - pregnancy brings on tremendous anxiety and confusion, along with the joy.

The greatest moments are those when you see the result pop up in a graph or in your statistics analysis - that moment you realise you know something no one else does and you get the pleasure of thinking about how to tell them.

Much of what I do in my job is think about whether relationships we see in data are causal, as opposed to just reflecting correlations. It's exactly these issues which come up in evaluating studies in public health.
