A recent study has shown that men control hunger better than women do, which goes a long way toward explaining why women are more likely to eat for emotional reasons, and why men always seem to drop weight more easily when they diet.

“Women have a much stronger reaction to food, such that whether they try to inhibit their desire or not, they have stronger signal [in the part of the brain that controls hunger perception and desire to eat],” study leader Gene-Jack Wang, MD explains.

Noise really does harm your health. New medical research shows what we all know intuitively.

Many cities have banned the so-called “boombox cars” with huge speakers that dominate the whole neighborhood with sound. That is, the laws say the sound of your stereo should not be heard more than 50 feet from your car. Some cities have also banned the use of subwoofers, the subsonic speakers that make your windows vibrate and can cause structural damage to buildings.

The laws are a good idea, but it is hard to get them enforced. Apparently most police officers either disagree with the laws or consider them too trivial to bother with.

Earlier studies had shown that the human brain can cope with only three noise sources, and only for a short time. Concentration is impaired, and eventually the brain just shuts down, and we can no longer think. It’s not just being “overly sensitive,” though some are more affected by sound than others. It is a physical process that we need to be aware of.

Researchers have now found that continous or repeated noise over 50 decibels can damage your heart.
