For Valentine’s Day, a fascinating collection of research and factoids about love, lust, relationships can be found in this article in The Independent. For example, here are a couple of items.

The lowest mortality rates were found in those who were named by their partner as a key source of emotional support and closeness, but who themselves actually named someone else as the one special person in their life.
Another item confirms that, indeed, we become stupid when we fall in love:
Scientists have discovered that certain parts of the brain become deactivated when we’re in love, including areas linked with negative emotions, planning, critical social assessment, the evaluation of trustworthiness and fear.
Biological studies have found that this phase of reduced cognitive function, during which faults are ignored, can last from one to two and a half years. This temporary state of delusion has a vital human function. If we immediately saw all our partner’s faults, we would be less likely to form a stable relationship in which to produce children.
