Philanthropy
In 2012 and 2013, Young partnered with Kiehl's to raise money and awareness for those with Autism. Young is the eldest of four brothers, two of whom are autistic; raising awareness of autism and raising funds to support those with autism is a cause that Young feels strongly about. "People with autism are just that – people first and foremost, with a condition that is autism...they have hobbies, they have loves, they have passions, but all of it is locked within this condition that is autism. There's no cure for autism at the moment, but with treatments at an early age, their thought potential can be unlocked." In addition to his charity work, Young has also fronted two government-funded youth campaigns: the anti-drug campaign Dance Works! 2012, sponsored by Central Narcotics Bureau in Singapore, and the Health Promotion Board in Singapore's Bounce Back Stronger campaign for youth resilience.
