Tuna Sushi Found High in Mercury

The New York Times recently did a study of the mercury content of sushi that was sold at 20 random New York City restaurants and found that most of the bluefin tuna that was being sold had mercury levels so high that a regular diet of six pieces a week would be beyond the levels acceptable by the Environmental Protection Agency. Similar results are found other places as well.

Sushi is often eaten because it is low in fat and high in protein but the mercury in it accumulates in the human body. Even small amounts can cause brain development problems, especially in children and pregnant women.

Why to Avoid Retail Therapy

A new study has found that people that are feeling down or gloomy are more likely to make big purchase decisions that they will later regret. These people are willing to pay up to 300 percent more for an item. Researchers say that sadness causes people to feel worthless and they often overspend as a way to feel better about themselves. The high that the person feels from overspending is short and they feel sorry about the purchase later, also known as buyer’s remorse. It is good advice not to go shopping while feeling down.

Sleeping is Essential to Learning

Research has shown that teenagers have internal body clocks and hormones that make it hard for them to fall asleep before 11 p.m. and hard for them to wake up before 8 a.m. Most high schools start classes around 7:30a.m., so students have to wake up very early. A National Sleep Foundation survey found that up to 28 percent of high school students fall asleep during their first class. A few high schools have recognized this issue and moved their starting times to around 8:30 a.m. When they did this, test scores and attendance increased.
