They have driven men to depths of depression, even to point of suicide, because they do not want to discuss their problem with anybody.

They do not want to discuss erection problem with their partner let alone a trained professional who deals with such things day in and day out. Erectile problems have also been reason behind breakdown of many marriages because of lack of communication between two people involved.

Probably biggest cause of sexual performance problems is stress. Not being able to leave woes of day at work will almost certainly lead to an erection problem of some kind, so it is important to make sure there is a break in day between end of work and before any other type of responsibility that needs to be taken care of: Sex in particular!

Another very common reason performance anxiety. It is a common reason for sexual performance problems because once it starts it often has a snowball effect which makes it progressively worse until it is almost impossible to have sex.

Stay Out of Sun!

Scientists believe life on earth started in sea. That's because before appearance of ozone layer, surface of earth was bathed in life destroying ultraviolet radiation.

Ozone is a form of oxygen. Whereas, a normal oxygen molecule consists of two oxygen atoms bound together, ozone is three oxygen atoms bound together. Ozone is much less common than normal oxygen. Out of two million oxygen molecules, only three are ozone. Ozone in stratosphere absorbs ultraviolet radiation, making it safe for life on surface of earth.

Ozone molecules in stratosphere are constantly forming and breaking up. Industrial development has caused release of chemicals called chlorofluorocarbons (CFCs). CFCs in stratosphere act as a catalyst, breaking down ozone molecules. CFC molecules are extremely stable. One CFC molecule can destroy over 100,000 ozone molecules.

CFCs are causing ozone to be destroyed faster than it is created. This has caused ozone layer to become thinner. In fact, a hole in ozone layer has opened up over Antarctica. In 2000, ozone hole measured 32.9 million square kilometers and extended over populated areas of Australia.

Exposure to ultraviolet radiation in sunlight can result in a skin cancer called "melanoma". According to American cancer Society, each year more than a million new cases of skin cancer are diagnosed. Melanoma is a highly invasive form of cancer. Even after treatment, a melanoma can metastasize. Once a melanoma has metastasized, it rarely responds to chemotherapy or radiotherapy. The life expectancy of an individual with metastasized melanoma is only a few months, and over 10,000 people die of skin cancer each year.
