Dr. Xand, being the older twin, stands just half an inch shorter than Dr. Chris. Both charismatic brothers are accomplished doctors in their own right, with Chris specializing in infectious diseases and Xand focusing on public health and tropical medicine. Across the UK there are stories and myths that need investigating. Dr Xand and Ashley examine the case of a woman who's raised thousands of pounds for her best friend’s cancer treatment – only to find out the diagnosis was a lie; they explore whether there is any truth behind the benefits of doing 10,000 steps a day, and if exercising actually helps you lose weight.
