Wildlife TV presenter and conservationist Chris Packham has always been fascinated by the natural world. As a child, he spent hours collecting slugs, snails, ladybirds and tadpoles from the garden to store in jam jars. He struggled to fit in at school and was bullied by other students. Chris knew he was different but didn't understand why. It wasn't until his forties that he was diagnosed with autism, finally providing an explanation as to why he experiences the world differently to other people.
