Ring finger vs index finger

On Thursday, Mummy was watching the documentary "Child of our Times" and one thing that Mummy thought was interesting was that we all have male and female brains in us but it's just a matter of how much more male or female brain does each child have.
How "male" or "female" we all are starts developing when we are a foetus in our Mummy's womb and this is determined by the amount of testosterone and hormones that the Mummy passes to the foetus via the umbillical cord.
And it seems that the way to tell is by looking at our ring finger vs our index finger. If you have more male brain then female brain, your ring finger should be longer than your index finger. So typically guys have a longer ringer finger than their index finger and girls have a longer index finger than their ring finger.
So the documentary was trying to do a study by measuring the babies fingers. For girls whose ring fingers seem to be longer than their index finger, the scientists think that chances are the girls will tend to be more tomboyish and boys with ring fingers longer than their index fingers maybe more feminine.
Mummy quickly looked at her own hands. Hey! My ring finger is longer than my index finger! But I don't think I'm a tomboy wat! Ok, ok ...not the most feminine girl around but I'm sure Daddy thinks I'm feminine enough to marry me... so that's what matters right?!
Oh and Mummy quickly looked at Caleb's fingers... ok, his ring finger is longer than his index finger so don't think he will grow up very feminine.
Anyway, enough of the sidetrack, Mummy thinks the documentary is really quite interesting. For those who have not watched it before, it's a documentary tracking the birth of 25 children from the time that they are conceived till they are 20 years old. These are all millenium babies so the studies that they are showing now are when they are just a few years old.
When I watch it, I find that the human body and our development is made up of sooo many complexities. It's really amazing. Truly, it is only God, who can think and put in so many intricacies into forming us and making us who we are. Imagine if he just made us out of matchsticks or something. We'll be so boring! I'm thankful. Thank you Lord!
