London, Sept 3 : The world’s oldest marathon runner Fauja Singh, who at the age of 100 has become the first person to sign up for the 2012 Edinburgh race, has revealed that the secrets to his fitness lie in ginger curry, and plenty of tea.

The Indian-origin sprinter, who has completed seven marathons since turning 89, admitted of having plenty of ginger curry and copious amounts of tea in order to stay fit for his daily 10-mile training regime.

“I am not a learned person in any shape or form. To me, the secret is being happy, doing charity work, staying healthy and being positive,” the Daily Mail quoted the Sardar as saying.

“If someone says I must stop running I ignore them - invariably they''re younger than me. The secret to a long and healthy life is to be stress-free.

“If there''s something you can''t change then why worry about it? Be grateful for everything you have, stay away from people who are negative, stay smiling and keep running,” he added. (ANI)
