All illnesses have some heredity contribution. It's been said that genetics loads the gun and environment pulls the trigger.
Interpretation
Genetics influence our health, but environmental factors determine how these genetic predispositions manifest.
The quote highlights the interplay between genetics and the environment in determining an individual's health. While our genetic makeup provides a foundation for potential health issues, it is the environmental factors—such as lifestyle, diet, and exposure to various conditions—that ultimately influence whether or not those genetic tendencies lead to illness.
In practice
This quote can be used in a discussion on public health policy to emphasize the importance of addressing environmental factors.
I think history would say that medical research has, throughout many changes of parties, remained as one of the shining lights of bipartisan agreement, that people are concerned about health for themselves, for their families, for their constituents.
I finished up my graduate degree in quantum mechanics, but underwent a bit of a personal crisis, recognizing that I didn't want to do that for the rest of my life. It was too abstract, too far removed from human concerns.
The brain is the most complicated organ in the universe. We have learned a lot about other human organs. We know how the heart pumps and how the kidney does what it does. To a certain degree, we have read the letters of the human genome. But the brain has 100 billion neurons. Each one of those has about 10,000 connections.
I believe God did intend, in giving us intelligence, to give us the opportunity to investigate and appreciate the wonders of His creation. He is not threatened by our scientific adventures.
I took biology in high school and didn't like it at all. It was focused on memorization. ... I didn't appreciate that biology also had principles and logic ... [rather than dealing with a] messy thing called life. It just wasn't organized, and I wanted to stick with the nice pristine sciences of chemistry and physics, where everything made sense. I wish I had learned sooner that biology could be fun as well.
Nobody gets argued all the way into becoming a believer on the sheer basis of logic and reason. That requires a leap of faith.
A strong intuition is much more powerful than a weal test. Normals teach us rules; outliers teach us laws. For every perfect medical experiment, there is a perfect human bias.
Imagine a survivor of a failed civilization with only a tattered book on aromatherapy for guidance in arresting a cholera epidemic. Yet, such a book would more likely be found amid the debris than a comprehensible medical text.
Biology is now bigger than physics, as measured by the size of budgets, by the size of the workforce, or by the output of major discoveries; and biology is likely to remain the biggest part of science through the twenty-first century.
The sciences do not try to explain, they hardly even try to interpret, they mainly make models. By a model is meant a mathematical construct which, with the addition of certain verbal interpretations, describes observed phenomena. The justification of such a mathematical construct is solely and precisely that it is expected to work-that is, correctly to describe phenomena from a reasonably wide area.
Early experience shapes the structure and function of the brain. This reveals the fundamental way in which gene expression is determined by experience.
I've been so lucky to have done two spacewalks. If you looked at your wristwatch, I was outside about 15 hours, which is about 10 times around the world. And, you know, there's a whole time dilation, distortion thing.
