I found this site on BBC Scince.
They write about such things as
The Science of Love
The three stages of love
The science of flirting
What makes you fancy someone?
Does love drive you mad?
Sensual signals

Hot stuff huh?
I was mot impressed with these:
Stage 3: ATTACHMENT
This is what takes over after the attraction stage, if a relationship is going to last. People couldn't possibly stay in the attraction stage forever, otherwise they'd never get any work done!
Attachment is a longer lasting commitment and is the bond that keeps couples together when they go on to have children. Important in this stage are two hormones released by the nervous system, which are thought to play a role in social attachments:
# Oxytocin - This is released by the hypothalamus gland during child birth and also helps the breast express milk. It helps cement the strong bond between mother and child. It is also released by both sexes during orgasm and it is thought that it promotes bonding when adults are intimate. The theory goes that the more sex a couple has, the deeper their bond becomes
# Vasopressin - Another important chemical in the long-term commitment stage. It is an important controller of the kidney and its role in long-term relationships ...
end of quotes.
If you get tired of reading all spam about how to get xxx then read BBC about everlasting Love!
