This July, I'm doing 100 Push-ups a day to raise money for GOSH Charity. Every day, more than 750 seriously ill children and young people from across the UK arrive at Great Ormond Street Hospital (GOSH). Every day, doctors and nurses battle the most complex illnesses and conditions and come together to achieve pioneering medical breakthroughs. This extraordinary hospital has always depended on charitable support to give seriously ill children the best chance to fulfil their potential.
