According to German Scientists, sexual excitement keeps your body younger for longer.
200 manly men were split into two groups. 100 were instructed to keep their eyes on the charms of ladies, while the others had to quit it. Possibly they were married?
At the end of five years of this pleasure/torture, the bird-watchers were shown to have lower blood pressure, slower resting pulse rates and lesser episodes of coronary artery disease. But almost certainly red slapmarks to the face.
The belief behind it is that sexual desire allows better blood circulation, which leads to a longer life. Perhaps there is something good to come out of Twilight then - long life ladies?
Dr. Karen Weatherby, a gerontologist and author of the study, says that the practice of ogling is almost at par with an intense regime of exercise, and can increase the man's life by up to five years.
She added, "Just 10 minutes of staring at the charms of a well-endowed female, is roughly equivalent to a 30-minute aerobics work-out."
Right, just off to do my workout now then.

And, of course, this is complete fiction. This "study" has been around for over a decade, but how many of you believed it to start with? Look back at the story and try and work out how they would have stopped 100 men from staring at boobs. Impossible. But it does send a good message. Never trust anything you read without a good solid source
