That's the number of people in Britain that have autism. Autism is a developmental disability affecting how someone communicates and relates to other people.
The National Autistic Society have reported that 71% of children with autism have mental health problems - they're often more susceptible because they find it hard to understand the world around them and explain how they're feeling.
So, how can you get involved? I found this quote on the National Autistic Society website from a volunteer befriender
"Maureen befriends Robbie. Sometimes they stay in the house with Robbie's little brother, watching videos or talking and playing. Robbie loves washing machines so sometimes they'll make pictures of washing machines, or sometimes they go out to electrical shops to look at washing machines!"
Did it make you smile? I certainly did - so much so that I told Julia (another blogger) about it. But more than that I think it shows how it's the simple things that can make a difference to someone's life. Pretty amazing.
