I think the most important thing you can do is ensure that you're educated about your own health and what's available for you, and also what should be available for you, because sometimes what you don't know is what you should know. What can you do to improve your health? What is up and coming in the world?
It's about ensuring that you have done everything you can to maximize your health, that your vaccinations are up to date and that when you're going to see a health care professional, you have an opportunity to do some reading beforehand so that you can use the time to ask pertinent questions that are important for you and your family.
