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.
The law of floatation was not discovered by contemplating the sinking of things, but by contemplating the floating of things which floated naturally, and then intelligently asking why they did so.
This new power, which has proved itself to be such a terrifying weapon of destruction, is harnessed for the first time for the common good of our community.
Population, when unchecked, increases in a geometrical ratio.
Given her deafness, the auditory part of the brain, deprived of its usual input, had started to generate a spontaneous activity of its own, and this took the form of musical hallucinations, mostly musical memories from her earlier life. The brain needed to stay incessantly active, and if it was not getting its usual stimulation..., it would create its own stimulation in the form of hallucinations.
The future depicted in a good SF story ought to be in fact possible, or at least plausible. That means that the writer should be able to convince the reader (and himself) that the wonders he is describing really can come true... and that gets tricky when you take a good, hard look at the world around you.
Only 20 percent of our longevity is genetically determined. The rest is what we do, how we live our lives and increasingly the molecules that we take. It's not the loss of our DNA that causes aging, it's the problems in reading the information, the epigenetic noise.
