In 2006, aged 12, he decided to start taking a selfie every day. Seven years on, more than two million people have now taken in seven years of his life in a 1:34m YouTube video showcasing the results of that decision. But that's not the end of things. Cornellier, now 19, plans to keep going until he gets old.
He told MailOnline: "The video will be me from 12 until literally wrinkles [form] on my face. Thinking about that is what makes me keep going. My entire life in three minutes. That's what inspires me to keep doing it."
