X-Ray is back on your screens for a new series and in our brand new feature '5 Minute Medic', presenter Lucy Owen will be visiting towns across Wales to test your first aid skills. With the help of an actor and a medical expert, she'll be finding out how well the public would cope in an emergency. Would you know what to do if you were faced with a common domestic accident like a burn or a knife wound? Could you save someone's life if they had a heart attack or stroke? Tune in to see how your knowledge measures up! High-caffeine fizzy drinks are growing in popularity among teenagers and young people - but unlike alcohol, it's legal for children to buy as many caffeine drinks as they want. But the drinks contain a stimulant which, if drunk to excess, can alter mood and behaviour and cause physical side effects. Should their sale be more strictly controlled? Rhodri Owen investigates. Home and contents insurance can be expensive and as the credit crunch bites, a growing number of people are reducing their level of cover to cut costs. But this could spell disaster if you need to make a claim. Our reporter Rachel Treadaway-Williams meets an insurance guru and travels to Cardigan to find out how much the local residents know about protecting their properties. And we'll be meeting a member of our viewer's panel, the X-Ray 100, who has transformed her Pembrokeshire home on a tiny budget. Angela Dooner has scoured her local charity shops, car boot sales and newspaper ads for bargain buys, second hand fabric and furniture to turn her house into a palace. But she didn't want to keep her thrifty talents to herself, so we challenged her to help X-Ray viewer Jayne Thomas revamp her children's bedrooms.
