In the final episode of Season 4 of "Under the Surface," we visit YouTuber Caspar Lee at his Influencer.com office to talk through his life's journey from childhood through to becoming an entrepreneur.

Caspar was diagnosed with Tourette Syndrome aged just 6 after his sister and parents noticed that he was making noises that he was unable to control. These un-preventable noises, referred to as tics, caused a moment of trepidation when on a family safari, finding themselves staring down an elephant ready to charge their car.

Caspar experienced a meteoric rise on YouTube, and declares that YouTube and gaming were a place of solace for him where he was distraction-free, keeping his mind quiet and his tics at bay.

Fast forward five years and Caspar is at the helm of four businesses but as so many people experienced during the Covid-19 lockdown, he couldn't avoid the stresses that arose in this time period. Following the lifting of lockdown, Caspar was diagnosed with Generalised Anxiety Disorder having found himself fearful of getting in a car and going out for dinner in public with his fiancée, which led him turning to therapy.

Caspar is now an advocate for Tourette Syndrome, helping the younger generation understand their diagnosis and to be okay with it. Tune in to hear how Caspar's diagnosis led him into a life of YouTube.
