Types of money
Money is any asset or good generally accepted as a means of payment by economic agents for their exchanges. Moreover, its appearance is due to the low efficiency of barter, which dates back to the Neolithic when the first human settlements began.
Many elements were used as money in different historical periods and in different cultures. In this sense, gold and silver have always been metals that have been used as currency because of their globally accepted value and ease of transportation.
Money evolved into paper money with the birth of banking, but it was not until the 20th century that metal lost its hegemony. At that time, the gold standard was abandoned and money was guaranteed by the backing of the State.

Estrogen, progesterone and testosterone are the three most important hormones for the maintenance of sexual desire. Therefore, it is normal that during a woman’s menstrual cycle, pregnancy or breastfeeding, her libido undergoes significant changes that affect her sexual activity. Likewise, some diseases negatively affect their secretion and the deficit of some of the so-called sex hormones can cause different sexual dysfunctions, both in men and women.
On the other hand, desire releases pheromones (hormones that favor sexual attraction) and adrenaline, which increases the heart rate and stimulates blood circulation. All this leads to overcome the phase of desire and enter the phase of excitement in which endorphins begin to be secreted increasingly until reaching orgasm, at which time the woman intensifies her pleasure with the release of oxytocin. It is important to know that this hormonal dance that takes place during sexual intercourse has a direct and beneficial effect on the body.
