I am so obdurate I do not change my mind.

My mind is changing about being a mum. I got a dog and the way I feel about it is a lot, and I realise maybe I would want to be a mum.

Based on how the scene felt I completely switched the dynamics.

I guess my learning about regulatory strategies is much better now, and I may have designed many clinical trials differently - for example, oral insulin.

I really wanted a role in Harry Potter and I never got one.

I talk too much.

I get a lot of abuse online because of my opposition to the assault on Gaza. The abuse is horrific, but I’ve learned to ignore it. The integrity of how you live your life is more important than what strangers think.

A deep sense that they will be fine in the world without me.

I would find a much better way of looking after my mum in her last three years of dementia. I did my best, but it was incredibly difficult to find the right kind of care unless you’ve got £3,000 a week to spend.

I worked in a supermarket on the Kings Road when I was 17, standing by the beers, wines and spirits to make sure people didn’t shoplift. They were such horrible employers that I didn’t care whether people shoplifted or not.
