What are tears and why we cry?
Tears are not identical and are distinguished by their cause and even by their chemical composition. Basal tears are present all the time and are meant to lubricate the eyes, nourish and protect the eyeball. The second type of tears is known as reflex tears, which are formed to protect the eyes from irritating agents such as wind, smoke, or onion. Finally, the third type is the one that comes after a quarrel, or after an impressive film. The tears we shed in these situations are called emotional tears, and it seems to contain more protein than the other two types, but the research is currently incomplete.
Scientists do not know exactly why we're crying. Theories are numerous. One alternative would be that crying occurred during the evolution to signal the situations in which people were in danger, without making too much noise. We can imagine that, at some point, we needed to develop a warning system that did not alert predators that we were vulnerable. The chemical composition of tears is similar to that of saliva. Among other compounds, tears contain proteins, salt and hormones.

Women cry more often than men. A survey estimates that women weep, on average, 5.3 times a month, while men - 1.4 times. Another study states that women would cry two to five times a month, while men only cry once. A survey by German scientists shows that on average women cry for six minutes while men only for two minutes, and in the case of women 65% of cases crying with sighing, which is only 6% of the situations in which men cry.

The headaches that occur after we cry are harder to explain. Some scientists believe that they are caused by dehydration, water lost with tears, while others blame the tension of the muscles that occurs when we are upset. A chemical reaction makes us cry when cutting onions.

The tears of joy are not very different from those caused by negative emotions.

Carmelia Albu – Ombudsman of the Public Broadcaster „Teleradio-Moldova”, in the service of community

Ombudsman service is an independent source of information, explanation and analysis of the Public Broadcaster’s programs and adherence to European standards and practices of broadcasting programs’ development.

Ombudsman is a mediator who handles complaints between a televiewer /radio-listener or a group of people and the Broadcaster. Ombudsman replies to the questions of TV viewers and Radio-listeners, receives and reviews complaints from people.

“Ombudsman” was first used in its modern sense in 1809 when the Swedish Parliament established the office of Justitieombudsman, who was to look after citizens’ interests in their dealings with government.

Later, in 1988, a similar service was established in media in France. It was a real "explosion” that caused the appearance of similar services in other world countries.
