Chris Packham invites us inside his autistic world to try to show what it is really like being him. For most of his life, broadcaster and naturalist Chris didn't tell anyone about the one thing that in many ways has defined his entire existence. Chris is autistic - he has Asperger's Syndrome, which means he struggles in social situations, has difficulty with human relationships and is, by his own admission, 'a little bit weird'. But what if there was a way of taking away these autistic traits? Would Chris ever choose to be 'normal'? Chris's long-term partner Charlotte discusses the problems Asperger's creates in their relationship, and Chris travels to America to witness radical therapies that appear to offer the possibility of entirely eradicating problematic autistic traits.

So what is behind the change? This is just one question of many that Javid aims to answer as he explores the science of drinking and the new evidence for the health risks of alcohol. Why do some people get drunk quicker than others? What is behind red wine's healthy reputation? Is a nightcap actually good for your sleep? Does lining your stomach work? And can alcohol actually make you eat more?
