Did You Know...

Your spinal cord stops growing when you're about 4 years old?? That means it's shorter than your vertebral column! (it stops at the L1 vertebrae, just below your rib cage)

Did you also know... 

Sometimes when I'm studying I'll have my earphones in but I won't actually be listening to anything because 

a) I can't pick something I want to listen to that won't distract me

or b) I just don't want to be bothered. 

Now you know. :)
