I read an article in an email message recently about how the lengths of children’s index and ring fingers can be used to predict how well students will perform on SATs. Kids with longer ring fingers compared to index fingers are likely to have higher math scores than reading and writing scores, while children with the reverse finger-length ratio are likely to have higher reading and writing scores versus math scores.

According to the article, different levels of the hormones testosterone and estrogen in the womb account for different finger lengths, which are a reflection of areas of the brain that are more highly developed than others. Exposure to testosterone in the womb is said to promote development of areas of the brain often associated with spacial and mathematical skills. That hormone makes the ring finger longer. Estrogen exposure promotes development of areas of the brain associated with verbal ability and tends to lengthen the index finger.

Scientists tested the link to children’s scores on the SAT by photocopying children’s palms and measuring the length of their index and ring fingers using calipers accurate to 0.01 millimeters. They used the finger-length ratios as a proxy for the levels of testosterone and estrogen exposure.

I tested this new found knowledge by looking at my family’s fingers. My brother T has longer ring fingers than index fingers. He’s definitely very good at math, especially mental math. My dad also has longer ring fingers than index fingers and is also very good at math. He teaches engineering. My mom and I both have longer index fingers than ring fingers and we are both better at reading and writing than at math. My brother A has longer index fingers than ring fingers but it’s hard to tell at the moment if he’s better at math or reading and writing since he’s only in second grade.

A good friend of mine create an amazing video that I’d like to show you. It’s a compilation of over 100 youtube videos of Christians from across the Earth. Even if you’re not Christian, it’s pretty impressive to watch. You can definitely tell a lot of time and effort was put into making the video.

Hey everyone! I know it’s been a long time since my last update, but this time I uploaded at least 60 new images to my gallery. I’ve been drawing a lot so I wanted to upload a lot all at once rather than only make a few uploads a day. I hope you’ll enjoy looking at them. Critiques are welcome.
