I don't want to lose my fitness. I'm 45. I have two babies. I've got a long way to go and I want to keep in tiptop shape. There's no magic bullet.

I'll tell you my routine - it's really exciting. I feed, I burp, I change diapers, I pump. And then I have a tiny window of time to myself.

I'd never say no to surgery in the future, because I feel like, as I get older, I'm going to face temptation more.

What I lack in energy, I have in wisdom.

I try to balance it out on the whole. Being a mum is always the priority. Next, it's taking care of yourself. Right now, I get to only work two days a week - it's a dream. I can't imagine how hard it is for mothers who work 40 hours a week.

I've been working so hard for the past eight years and I'm tired - but I'm also deliciously tired because what a wonderful life I've lived.

It's kind of ironic that if I get my Ph.D., I'll be a real doctor
