Dr Bryan Betty joined Jack Tame to chat about the truth behind some 'old wives tales':

Whether you’ll get a cold if you go outside with wet hair. 

If you’ll get arthritis if you crack your knuckles. 

Whether you should chew your food 30 times before swallowing. 

If you’ll get square eyes watching too much television. 

If eating Carrots will give you better eyesight. 

Is the five second rule for dropped food accurate?
