"There is no such thing...I will continue to be the chairman and chief mentor of Infosys until the age of 60...I am 56 years and 10 months now and will continue... Unless I am mentally or physically incapacitated," he told reporters here on the sidelines of the 22nd annual general meeting of the Nasdaq-listed, Bangalore-headquartered software major.
