Although it sounds strange, if a man's index finger is longer than his ring finger, he could run a lower risk of developing prostate cancer. That, according to Warwick University and the Institute of Cancer Research in Britain. So, just how much of a lower risk do you run if your index finger is longer than the fourth digit? Well, the study finds in older men, the risk is reduced by a third. For younger men, it's even greater. The study says it could allow physicians a fast way to see which men need to have regular prostate exams.

Here's my question, what if your index and ring fingers are the same length? I can't tell which one of my fingers is longer.
