Growing up with my family gave me some of my best memories. I'd like to have a family of my own - slip away for a bit and do nothing but spend those early years with my children.

Everything in my career is my decision - every picture, every outfit. You get one chance at this, and I never saw myself as being a puppet.

From as young as I can remember, I always wanted to be a singer... My mum taught me 'Going Down the Garden to Eat Worms' for a competition when I was about 4.

My idol was Marilyn Monroe, who was a size 16, I think, and curvy in all the right places. I will never be stick thin. I remember a shoot where I had to get into these tiny hot pants, and I thought, 'God, I wish I hadn't eaten.'

Unfortunately, the mechanism for doing philanthropy in a structured way isn't yet in place in India. I already do a fair bit and support various causes such as education, sanitation, health. But selling costly drugs at affordable prices is philanthropy in itself.

I see more people taking charge of their well-being through the use of data and digital sensors, wearable health bands, and smartphone apps that can track and quantify everything from their heart rate, blood pressure, and sleep quality to steps walked and calories consumed.

The 2000 Durban conference prompted action, and since then, great strides have been made in global health and the fight against HIV/AIDS.

Here's how I look at it: Life is full of challenges. Everybody has them. For some, it's health or family crises. I had a financial challenge.
