Exercise directly conditions the cardiovascular system, whereas benefit to other systems or conditions is somewhat less direct
By Sandee LaMotte, CNN Published 7:05 PM EDT, Tue August 8, 2023 Walking a minimum of 4,000 steps a day significantly reduces your risk of an early death, while taking 2,337 steps a day will reduce your risk of death specifically from cardiovascular disease but “more is better,” according to a new meta-analysis of studies. “The more steps you walk, the better the effects on your health, and every increase of steps by 500-1000 steps/day may be associated with significant mortality reductions,” first author Dr. Maciej Banach, deputy editor-in-chief of the European Society of Cardiology, said in an email. Anything below 5,000 steps a day is considered a “sedentary lifestyle,” according to the study. The fact that it takes fewer steps to reduce risk of cardiovascular disease is not surprising, said Dr. David Katz, a specialist in preventive and lifestyle medicine who was not involved in the study. “Exercise directly conditions the cardiovascular system, whereas benefit to other systems or conditions is somewhat less direct,” said Katz, president and founder of the nonprofit True Health Initiative, a global coalition of experts dedicated to evidence-based lifestyle medicine. The study’s methods were “robust and state of the art,” and support what doctors often tell their patients, Katz said. “First, any exercise is better than none — with significant cardiovascular and overall health benefit at quite modest levels,” he added. “And for the range of activity that pertains to the public at large — the more, the better!”

By Deidre McPhillips, CNN Published 1:49 PM EDT, Fri September 8, 2023 Early data from South America shows that the flu vaccine has cut the risk of hospitalization in half this year, a hopeful sign that the vaccine will provide a similar level of protection in the United States as the country heads into its own respiratory virus season. The Southern Hemisphere typically experiences its flu season a few months earlier than the United States, and trends from that region can help the US prepare for the fall and winter. This year, mid-season flu vaccine data from five countries – Argentina, Brazil, Chile, Paraguay and Uruguay – shows that vaccination has reduced the risk of hospitalization by 52%, according to a report published Friday by the US Centers for Disease Control and Prevention. The data are based on about 3,000 patients who were hospitalized between late March and early July. People who had gotten the shot at least two weeks before the onset of symptoms were considered to be vaccinated, and the analysis focused on certain high-risk groups who were prioritized in the vaccination campaigns, including children, people with preexisting conditions and older adults. So far, the specific virus strains that have been detected in US this year have shown a similar pattern to those that were identified in South America. While these patterns are not yet certain, they offer an “encouraging outlook for vaccine protection” in the Northern Hemisphere, the researchers wrote in the new report. Annual flu shots are available now and the CDC recommends them for everyone 6 months of age and older in September and October, especially including very young children, people with preexisting health conditions, pregnant people and older adults. The agency is rolling out new ads it hopes will increase confidence in the vaccines with a clear, straightforward message: “The flu vaccine won’t keep a person from getting sick, but it will tame that infection, taking it from “Wild to Mild” — the tagline for the new campaign.

In the sentence “The flu vaccine won’t keep a person from getting sick, but it will tame that infection” the word won’t is the contraction of ‘will not’ and a modal verb. Select the option that states this modal verb meaning and a word that could replace it without changing the context, respectively:
While that makes it the country with the highest number of murders of green activists anywhere in the world, other countries in Latin America also proved deadly. …………., Brazil recorded 34 murders of defenders of the environment. Mexico 31 and Honduras 11. The Amazon region saw 39 killings, with many of the victims from indigenous communities.
