Children who are touched and hugged by their mothers are more relaxed and have calmer minds.

The research has some serious limitations. The possible unknown factors are driving differences in amounts of touch and in the children’s brain development like genes.

Uncompleted goals are particularly likely to stay on your mind.

Smit surveyed 103 employed people. He asked them to report which goals they completed and which goals they left unfinished at the close of each day. Before bed they reported on how much these goals had occupied their thoughts.

The incomplete goals intruded their minds more. If participants rated a goal as somewhat unimportant it wasn’t a problem.

This effect applied only to participants who were involved more in their job. Those who were less invested in their jobs were immune to the late night thought intrusions.

Researchers recorded a fragment of speech from middle-aged women with rheumatoid arthritis and breast cancer.

They found that those who swore in the company of other people had increased depression. What more, those same people also lost social support.

The study has its limitations, as the sample. Swearing by women has an adverse effect on their social support. Particularly, societal norms dictate that women shouldn’t swear. The same study performed with young men may produce another result.

Intelligence is connected with sperm quality

Researchers found correlations between intelligence and sperm concentration, sperm count, and sperm motility. The sample consisted of 405 U.S. Army Veterans. Scientists took notice of age, body mass index, days of sexual abstinence, service in Vietnam, or use of alcohol or drugs.

Intelligent men are always attractive

By |April 8th, 2017|Categories: Relationships|Tags: , |

A group of 204 women were evaluated based on the long- and short-term appeal of videos of 15 men. They had a known level of intelligence and physical features.

Findings say that women look for geniuses for both one-night stands and for long-term relationships.

However, other studies suggest that women don’t care about the brain for short-term relationships.

A high-sugar diet shortens the lives of flies…

even after their diet improves. This is because the sugar diet leads to long-term reprogramming of gene expression.

The gene is also important for humans, so the findings may have broad implications for us.

The research team fed a healthy diet containing 5% sugar to one group and the other group was given 40% sugar. After three weeks both groups of flies ate healthy food. Flies live about 90 days, and they ate sugar for 23% of their life. This corresponds to approximately 17 years of our human life.

Even after healthy diet, the flies with a high-sugar diet started to die earlier average had 7% it means 5 human years.

Maybe now the question rise: is it better live longer or more pleasure?

Drugs work a little bit better than a placebo

By |April 6th, 2017|Categories: Healthy|Tags: , |

In 2008, a psychologist analyzed all the test data on drugs used for curing depression. He concluded that the extra benefit of the drug versus the placebo was not meaningful. He said this was for those with mild to moderate depression.
