We've often heard that excess cholesterol in the blood is one of the main factors of heart abnormalities. Cholesterol is too low was as dangerous.

Cholesterol is a type of lipid molecules in the bloodstream. Cholesterol is produced by the liver and is needed for metabolic processes. Cholesterol is beneficial to the formation of cell membranes, some specific hormones, and other necessary tissues.

Cholesterol levels in the blood of normal is less than 200 milligrams per dL, bad cholesterol (LDL) less than 130 mg / dL, HDL cholesterol of more than 45 mg / dL, and triglycerides less than 200 mg / dL.

Someone declared excess blood cholesterol levels or high cholesterol if the total cholesterol levels reached more than 240 mg / dL. Excess cholesterol can cause buildup of fats that clog arteries.

On the other hand, cholesterol is too low or less than 160 mg / dL was also not recommended because it is dangerous to health.

Research shows that pregnant women who had total cholesterol levels are too low at high risk of premature delivery. The number of total and LDL cholesterol is too low is also associated with depression, anxiety and cancer diseases.

Long practiced by ­Buddhists, mindfulness is now well established in the West and widely used by those seeking psychological or spiritual change in their lives. Advocates believe this meditational practice can help alleviate a variety of mental and physical conditions, including obsessive-compulsive disorder and anxiety. But what is mindfulness and how might we use it?

SEIZE THE MOMENT
Mindfulness is concerned with the present; with keeping your consciousness alive to the present moment. This may appear a simple task, but is harder than it sounds. Most of the time, our minds are taking us back into the past or into the imaginary future.

To help us to engage with the present moment, breath work is a great help, because unlike our mind, it is always present. So becoming aware of your breathing — in and out, in and out — is a wonderful start to becoming present.

Sperm quality in men is not only determined by the condition of the reproductive system, but also influenced by bone health. If you want to have sperm quality, make sure the framework of the body is always maintained his health.

A study at Columbia University showed that the healthy bone to produce more osteocalcin, a protein that make up the bones and teeth. Protein content is what will affect the fertility of male reproductive system.

In that study, men whose bones are not many produce osteocalcin tend to be less potent difficult to fertilize their partner. Conversely, if osteocalcin produced in the bone more and more, the quality of male sperm would increase so that more potent.

When investigated further, osteocalcin was associated with the production of the male sex hormone testosterone. High levels of osteocalcin which trigger the production of more testosterone, so men are capable of producing higher quality sperm.

The findings are then followed up with an experiment on male rats. When male rats were injected ostgeocalcin, testosterone production increases, which produced more sperm quality, and certainly more potent to inseminate female mice.

"The relationship between bone health with the reproductive system were observed only in men. We did not find similar effects in women and female rats," said the researcher, as quoted by Gerard Karsenty of Sify.com, Monday (02/21/2011).

This finding is quite interesting because the relationship between the bone with the reproductive system previously only focused on the function of the gonad gland, the gland that regulates male and female genitalia. The higher activity of the gonad gland, the more bone cells produced by the body.
