I basically believe the medical insurance industry should be nonprofit, not profit-making. There is no way a health reform plan will work when it is implemented by an industry that seeks to return money to shareholders instead of using that money to provide health care.

To date, embryonic stem cell research has not produced a single medical treatment, where ethical, adult stem cell research has produced some 67 medical miracles.

Here in Silicon Valley, I have taken part in hundreds of conversations trying to convince people to dive in and become entrepreneurs. All too often, innovators with good, safe, jobs are unwilling to put their family's access to health care at risk by walking away from company-backed medical insurance.

Synergy and serendipity often play a big part in medical and scientific advances.

Advances in science and medical research and public health policies have meant that life expectancy for Australians is one of the highest in the world.
