Medical notes this week…
More than 31 million people are injured and require hospital care each year… and a new study has figured out that non-fatal injuries cost nearly two trillion dollars annually. Medical costs account for only about 170 billion of it… while permanent disability costs more than 200 billion. The biggest cost is in the loss of quality of life as a result of injuries–researchers put that total at nearly one and a half trillion dollars a year. Falls, being struck by an object, and car crashes account for about half the injuries…and experts say they’re almost all preventable.
About three million children are diagnosed with scoliosis or back curvature every year, and now researchers have found a possible cause. A study in the journal Nature Communications shows that children with severe scoliosis are twice as likely as children without the disease to carry a gene that makes it hard for their bodies to process manganese in the diet. Scientists say modifications in the diet may help, but they caution against manganese supplements for now, because too much manganese is also dangerous.
If you thought volunteering to help out a co-worker is a good thing… think again. A study in the Journal of Applied Psychology shows that it’s better to wait to be asked before you help. Scientists say helpers who jump in without being asked often don’t have a good handle on what they’re doing, so they don’t get much gratitude for it… and the person being helped starts feeling incompetent. Better to stick to your own business, researchers say… until you’re asked.
And finally… what kind of person swears the most? According to a study in the journal Language Sciences, it’s people who are highly intelligent. Researchers say people with a large vocabulary and who are fluent in language are good at creative swearing… and they’re not afraid to use it. Scientists also say people who swear a lot are honest with others… and more true to themselves.
