More reasons to have sex

Melbourne's newspaper The Age reports that sex will keep you healthy in a number of ways:

• Sex has been linked, in women, to a heightened emotional awareness.
• Semen is a mood-enhancing ingredient. (I have been telling this to SWMBO for years).
• People who have sex once or twice a week have levels of immunoglobulin A (IgA) that are up to a third higher than their more restrained peers.
• Men who have orgasms twice a week are half as likely to die early as men who orgasm less than once a month.
• The more frequently men ejaculate, the less likely they are to develop prostate cancer.
• If middle-aged men have sex twice a week or more they also have a lower risk of heart attack.
  

Sounds good to me...Here is the whole report.
