Lesbians and the neural tube

Instead of learning about Neurology (which is definitely what I should be doing) I decided to talk a little here. Today I have mostly been homosexual, and as such came across this lovely site, it's brilliant! I just decided that on evaluation, girls are just nicer, see examples. I realise that the social stigma and inability to create people could make life less easy but you know, they have smaller shoulders and their hair is softer. I think you should agree.

On a marginally more academic subject I have been marvelling at the neural tube. For those who may not already know your brain starts out as a tube. It goes something like this...
Week 1: sperm reaches egg, starts to divide
Week 2: Fair few cells in a big blob
Week 3: Blob has organised into a sheet of 3 layers of different cells (endoderm, mesoderm and ectoderm) which will for all the different tissues and organs
Week 4: Sheet begins to fold up with a groove in the middle
Week 5: It forms a tube
Week 6: one end of the tube begins to grow massively and fold up - this will be your brain, the other end will be your spinal cord (all the other organs are growing too by the way
Somehow at week 9-10 there is a person about the size of the end of your little finger will fully developed organs which will then simply grow in size.

I like the idea that complex things are simply a long sequence of simple things stacked up on top of each other.
