As explained Daniel E. Lieberman, paleoanthropologist at Harvard University, in his book The history of the human bodyIn the United States, medical care for a cardiovascular patient costs an additional $18,000 per year.

Therefore, if just 25 % more of the population were convinced to get fit, it would save $58 billion a year on cardiovascular disease care alone. Roughly double the annual research budget of the National Institutes of Health (NIH): that is, It's better to prevent.

The power of prevention

Prevention, then, seems to be a much more intelligent aspiration, for which we must all fight with greater effort, at least more than simply putting all our eggs in the basket. the care or resolution of medical problems.

Prevention is not becoming obsessed with exercise or diets. Much less entrust yourself to the paleo diet, which is in any way a pseudoscientific construct: there is no ideal and exemplary way of life for hunter-gatherers. There is not even the idea of a paleo diet, because this should be a set of diets very different from each other, as Lieberman points out:

By way of analogy, trying to understand what the human body is adapted to by looking only at hunter-gatherers would be like trying to understand the result of a football game by looking only at a fragment of the second half.

The most effective prevention would simply happen, according to This studio of The Lancet, by eating a diet rich in fruits and vegetables, not smoking, exercising moderately and not drinking alcohol excessively. Doing this is enough to reduce cardiovascular disease rates by 50 %.

For this reason, precisely, develop non-fattening food It would not solve one problem but it would amplify others, and it is smarter to be safe than sorry, as I explain in the following video:

According to A study, lWomen are less likely to say yes to an image of a man holding a cat. That's the conclusion of a completely counterintuitive study (don't women like cats?) from Colorado State University. The study surveyed a total of 708 women between the ages of 18 and 24 in an online experiment.

The thing is, according to the authors, that men who held cats were seen as less masculine, more neurotic, pleasant and open, and less friendly. That is, it is likely that the findings are the result of deep-rooted cultural stereotypes about dog and cat owners.

Lack of masculinity

In the study, when a group of women were shown the cat-free image of one of the subjects, the women's 38% said they were likely or very likely to date him occasionally, while the women's 37% said they would consider a relationship. would be with him.

But an image of the same man holding a cat got the respondents thinking, and those numbers were reduced to 33% for each category. Meanwhile, the proportion of women who said they would never consider getting involved with him increased from 9% to 14%.

In comparison, positive ratings for the second subject did not decrease significantly when he was photographed with a cat, but women were more likely to rule him out as a potential partner.

If you squint, your cat will like you better: no joke

When photographed alone, 40% respondents said it would be unlikely or certain that they would not go out with him occasionally. But it increased to the 45% when a cat joined it. Similarly, 41% said he would be unlikely to be considered for a relationship, but 45% said the same thing when they saw him with the mascot.

Thinness

Everything seems like stereotypes, according to the authors, just as happens with that of a woman with cats, which is culturally associated with a woman with mental problems (the crazy cat lady):

Cat emotions aren't that difficult to interpret, but women do it better than men

Cat owners did not differ from others in their symptoms of depression, anxiety, or their experiences in close relationships. Our findings, therefore, do not fit the notion that cat owners are more depressed, anxious or lonely.

Mutatis mutandis, the photographs of thin women They also tend to be more successful among the male market because that image carries cultural stereotypes, in addition to pressing the button on the handicap principle (sexual selection traits act as signals of ostentation, showing the ability to afford to waste a resource simply for the sake of waste), whether suggesting that being thin is something exclusive as it is, for men, drive a car-dick:
