A Swedish inventor has designed a watch that apparently calculates a person's life expectancy - and even counts down to the time they will die. Dubbed the 'death watch', Tikker was created by Fredrik Colting.But far from being morbid, Mr Colting calls it 'The Happiness Watch' and claims it has been designed to help people make the most of their life and cherish the time they have left.To set up Tikker, the wearer fills out a questionnaire by entering information about their medical history, including allergies or illnesses.They are also asked whether they drink or smoke and if there are any instances of cancer, diabetes and other diseases in their family.(dailymail.co.uk)Bakudaily.Az
