Over the past year, arts student Ke Weiliang has been gradually deleting his numerous social media platforms such Twitter, Instagram, Snapchat and Tumbler. Last month, he announced on Facebook that he had gone on a "social media detox... for the sake of my mental health". He wanted to delete his Facebook account too, but decided to keep it for its networking opportunities.

At age 24, Mr Ke is the very definition of a millennial and a digital native, someone who grew up with all the conveniences of Google, Wikipedia, Facebook , Youtube and eBay. His is a generation that takes it for granted that you can have all the information you need on a subject at your fingertips, and you can instantly connect with anyone from anywhere in the world for free.

But Mr Ke started to swim against the tide of his generation, famous for its heavy social media usage, when he felt a growing unease within himself. He says: "I was developing a tendency to worry about how many likes I was getting for my posts. I kept checking my posts to find out if my close friends had liked or favourited them - or, if they hadn't, why. It was starting to affect my self-esteem."
