Mark is in his 50s and should know better by now honestly but here we are.

His online creative name is ShutUpMark and he can be found on Etsy, Facebook and Instagram. ShutUpMark can also be found on YouTube making little stories about life after discovering that he had ADHD at the age of 54 and how he's now making a living in the creative industries. He's been many things in his life, from Pollution Inspector to professional poker player but is finally now content with a camera, a laptop, a graphics tablet and a working knowledge of Photoshop.

People still tell him to shut up all the time.
