Is the NHS giving hip replacement patients sufficient aftercare? We hear from people who have had metal-on-metal hip replacements go wrong - sometimes without any outward signs to trigger medical intervention. Official guidance does not recommend annual checks without due cause, but should all metal-on-metal hip implants be X-rayed every year - just in case? Also on the programme - sick of your phone running out of juice? We look at which smartphone apps drain the most power from your battery? And why running - that most basic and cheapest physical activity - has become such big business. Who cashes in every time you go jogging?
