It has been said that human relationships are very important for one's health. It has also been found that women's chatting to each other increases levels of progesterone which boosts well-being and alleviates anxiety and stress. Progesterone is so positive to a woman's overall being that it even revealed to affect a woman's answer when being asked if they would "risk their life for their friend".

Studies show that facial expressions can trigger negative feelings. Botox, paralyzing the muscles in the face, has been revealed that causes humans to loose expressions and even have a harder time to identify other's. Botox not only limits a person's ability to frown, but also to feel sad. Expressions of the face and emotions seem to show a strong relationship.

There has been debate whether bisexuality is just a face. Some women seem to lose their interest for both sexes over time. Bisexuals tend to feel a strong erotic attraction towards both sexes. It has been found that bisexuals are even more common than women who are attracted to same sex. It is difficult to know much because usually they tend to change from time to time- attraction to same sex and attraction to opposite sex.

One more time, the forever-debated "Nature and Nurture" is on. The so called "vulnerability genes" that make us susceptible to certain things, seem to matter as equally as the environment you are in. In other words, not only does our nature affect what we're susceptible to, but also where and how we are raised. If our mothers smoked during their pregnancy, then this can affect us as much as our genes. A positive environment with benefit these individuals immensely, making their situation more malleable in a way. Some may even be more affected by negative environments that others. This genes have now also been nicknamed "malleable genes".

Lucky enough, unfortunately, we have a strong tendency to save bad, negative memories. Yes, negative memories remain in our minds more than those happy-go-lucky memories do. They are live, and vivid and every time we come across them, they haunt us. Our brain reacts more profoundly to negative stimuli, kind of like a risk detector. As humans we have been created to avoid danger, and so it seems that our mind is equipped to do it right. It has also been found that in married couples there is always more negativity than optimism, but a balance of a ratio of 5 to 1 should be maintained.
