You may be surprised to learn that nutrition and sex are closely linked - and it has nothing to do with chocolate!

Science has linked reduced sexual performance and increases in infertility to compounds in our toxic environment, poor nutritional habits and excess stress - all factorsthat are, to a certain degree, within our control.

According to American Infertility Association, an estimated 10% of couples in U.S. are infertile. And around world, lower sperm counts are being reported in men, with blame belonging, in part, to increase of toxic and hormone-active chemicals in environment.

This morning you took a bath. The warm water feels so nice during cold winter day. There was some funny skin itching on you back. You looked in mirror, turned this way , that way. There is small mole on your back You remember this spot had been there for years, since childhood. Did this spot get that strange itching?

Several types of skin tumors exist. Many are slow growers. Many give rare metastasis. Simple removal cure majority of skin tumors.

Melanoma brings troubles big time.

Melanos = black, oma = tumor.

You can detect melanoma by self-exam. Skin cancers show themselves much easier than any other types of cancer.

In same time you can cure melanoma by simple surgical resection. However, catch this tumor in early stage. Late stage metastasize. Surgeon can not cut off every metastasis in your body.

There are numerous sites dedicated to melanoma self-exam. Just type in word "melanoma" into any search engine. Follow instructions.

Fair skin people have more chances of getting melanoma. However, dark skin people develop melanoma too.

Everybody has moles. Women even use moles to charm. How to find if your mole became dangerous?

Dangerous signs include ABCD:

Asymmetry

Border

Color

Diameter

A- asymmetry. Suspicious mole does not look like a round or oval blot. Often, early melanoma looks rather like a blot with an odd shape.

B- borders. Borders become irregular, uneven, fuzzy. The edges of blots become notched.

C- color. Color of normal mole should be more or less homogenous. Change in color is very suspicious . There are shades of brown, black, tan, red. Mottled color is suspicious.

D- diameter. Change in diameter is suspicious too. Mole that is bigger than 6 mm is suspicious. Everybody compares 6 mm to a pencil eraser (though few people actually use it extensively). Just to get idea about borderline size.

Besides ABCD there could be other signs of dangerous mole:

E - enlargement and elevation over time
