Alright, so I've had a busy couple of days and haven't posted a fact for 2 days. So, as always, you will be getting today's fact along with the 2 I missed. :) I also realise that I haven't been citing where I have been getting my facts just in case people are interested and want to learn more. Just to be clear though, none of the facts came from my own brain but from other people's studies.
