Are you considering a vasectomy reversal? Thousands of men undergo vasectomy each year as a permanent means of birth control, yet for some of these men life brings unexpected turns, which leads them to change their mind.

Pheromones are natural biochemicals released by animals and insects that help to communicate sexual interest to members of the opposite sex. These biochemicals (pheromones) influence mating, fertility, and child rearing.

In humans, pheromones have been shown to affect women's menstrual cycle and a man's and/or woman's perceived attractiveness to the opposite sex. Pheromones are similar to hormones in our body that tell our cells and body what to do

How Are Pheromones Detected By Humans?

Scientists state that the organ responsible for detecting pheromones in mammals is the vomeronasal organ located in the nose. Synthesized human pheromones like androstenedione and estratetraenol, applied to the skin, have been studied and shown to dramatically increase the frequency of socio-sexual behavior in participants using the pheromones as opposed to the...

History of asbestos.

There are four main types of asbestos; Amosite (brown fibers), Anthophyllite (gray fibers), white Christie, and blue Crocidolite. Chrysotile has curly fibers while the other three have rod like fibers. These fibers fragment into dust quite readily and waft into the air. They can adhere to skin or clothing and are easily swallowed or inhaled.

Half a century ago, asbestos was hailed by many as a miracle product. They said nearly anything could be made from this mineral. It as used as an additive to reinforce mortar and plastics. Asbestos fibers can also be separated into fine threads that do not conduct electricity and are unaffected by heat or chemicals.

Use of asbestos drastically increased during World War II. Shipbuilding incorporated asbestos extensively in freighters and support vessels to insulate boilers, steam pipes and hot water pipes. Asbestos became the miracle construction material as it was readily obtained, proc... [more]
