Then someone came up with the "scientific" proof that "all medical examiners know this" line of reasoning that hands were different. The hands are the smoking gun on if a person is a man or a woman. Well I remember looking at these pictures a year or two ago and looking at my hands. I am not a dude nor do I want to be a dude. I am very much a woman and I like being a woman. By this hand criteria I am a dude. So of course I started doing some research and found that your hand shape and size have a lot to do with how much testosterone your mother had in her when she conceived and what she past on to you. Michelle might very well be Michael but you need to use different criteria than just the hand test.
If your left hand resembles image A:Mine resembles A, if you want to know more click on the link above picture.
Your hand size can tell if you are more prone to cancer or how well you might do on SATs.
