> The definition of vaccine (provides immunity)
"That technical coarseness might help explain why several historical vaccines have been assumed to be sterilizing. With measles, for instance, scientists initially lacked the tests needed to show them otherwise" (from the Atlantic article)
> recession (two quarters of contraction),
"Is Recession Staring Us Down? Already Upon Us? Here’s Why It’s Hard to Say. The U.S. may register a second straight quarter of economic contraction, one benchmark of a recession. But that won’t be the last word. Most economists still don’t think the United States meets the formal definition, which is based on a broader set of indicators, including measures of income, spending and job growth." (New York Times)
> woman (female with XX chromosomes),
"Gender is a complex interaction of underlying biological difference and social norms, not a simplistic either/or" (The Atlantic)
> freedom (from doing what you want to "the ability to choose")
"Freedom Means Doing Whatever You Want?"
"Before getting to the debate, we have to mention two key ideas about what freedom means. The first is that no one has absolute freedom in the sense of having the power to disengage completely from societal norms and values. The second idea is related to the fact that freedom doesn’t just entail the choice between one action or another. It extends to thoughts and emotions as well. All of us have some freedom to choose what we think and feel. We also have to consider the responsibility that is attached to the willingness and ability to choose." https://exploringyourmind.com/freedom-mean-doing-whatever-yo...
> family (husband, wife and kids),
"What is a “family”? Statistically, it is no longer a mother, a father and their biological children living together under one roof (and certainly not with Dad going off to work and Mom staying home). Although perception and acceptance often lag behind reality, there is evidence that a new definition of family — while far from universally accepted — is emerging." (New York Times)
