Today marks the last day of the Social Media Detox, Brenton High’s fundraising campaign for new sports equipment. At the start of the detox, over 100 students had been persuaded to stop using social media, in ANY form, for seven days. This meant no messaging friends, no posting photos, no blogging – nothing. They had been promised money by family and friends for each day spent without using social media. They were excited. They were nervous. But could they do it

I lasted four days. On Monday, my classmate and I spoke about what we did at the weekend – it felt really strange not to already know what he had done.

The detox raised a total of 1,632.82 for new school sports equipment! Well done, everyone who took part!
