We have been trained not to think about our health care until there's a problem.
Some genetic variants can be informative about one's risk for Parkinson's disease and Alzheimer's disease.
It's not just professional athletes and soldiers who are at risk from traumatic brain injury. More than 1.7 million people a year sustain a traumatic brain injury, and about 50,000 of them die each year, according the Centers for Disease Control. There are both emotional and financial costs from these injuries.
It's worth knowing more about the complicated environmental and genetic factors that could explain why traumatic brain injuries lead to long-term disabilities in some people and not in others.
One of the big drivers for me is that health care is a very elitist system. As much as we try to make it free and democratic for all, the reality is that it's expensive and not all therapies are accessible to all people. So I have been very focused on making sure that we democratize genetic information so it's available to everyone.
People are used to dealing with risk. You are told if you smoke, you are at higher risk of lung cancer. And I think people are able to also understand, when they are told they are a carrier for a genetic disease, that is not a risk to them personally but something that they could pass on to children.
I think we're just scratching the surface. One of the most exciting aspects of 23andMe is that we're enabling you to watch a revolution unfold live during your lifetime, and I think that the decoding of the genome, in my opinion, is the most fascinating discovery of our lifetime, and you get to be part of it.
I think there's a lot of misunderstanding about genetic information and what you can and cannot learn. One of the things we try to do is educate individuals that knowing information is empowering.
If you don't read it, you don't know. I mean, that's why I have a PR team. They read it and tell me if there's something, and that keeps you focused. I know my family and me well enough; why do I need to read about myself? I'm not going to change, I'm very stubborn in this way. I am what I am.
One of the things that got me interested in genetics was the relationship between genes and environment. We are all dealt a certain deck of cards, but our environment can influence the outcomes.
The fact that my environment influences my life so much - and that my environment is in my control - gives me a great sense of empowerment over my health and my life.
I think that for people who are trying to make a difference, you have to start the company being naive. You wouldn't do it if you understood all the work. I work a lot. I wish it was easier.
