Finger Reading

NBC News 5 in Chicago just read a story about the length of your ring and index fingers and their relation to prostate cancer. Some study published in the UK reports that males have a ring finger longer than their index finger, their chances of getting prostate cancer increase. So of course I googled what's common as my fourth finger is definitely longer than my second. Apparently, it's quite common for males to have a longer ring finger so I'm not sure how much validation we should give to this study. I'm thinking not much.
