One of the biggest challenges to medicine is the incorporation of information technology in our practices.

As the father of six children I know very well the challenges technology poses to our families.

If we invest in researching and developing energy technology we'll do some real good in the long run rather than just making ourselves feel good today. But climate change is not the only challenge of the 21st century and for many other global problems we have low-cost durable solutions.

Champagne if you are seeking the truth is better than a lie detector. It encourages a man to be expansive even reckless while lie detectors are only a challenge to tell lies successfully.

I had a great drama teacher and he sort of made out drama school as this incredibly difficult thing to get into: 6 000 people apply every year and some of the schools only have 12 places. It's a phenomenally difficult thing to get into. And that excited me - I wanted that challenge.

I want the municipality to be a helping hand to the man with a desire of sympathy to help the fallen when it is not in their power to help themselves.
