"I have noticed that our officers continue to fall prey to lifestyle diseases which to my mind are preventable," Rai, GOC-in-C of Eastern Command, said at a medical conference at the Command Hospital.
He said awareness through higher education can provide a solution.

"We need to nurture good military values at all times," he said, adding that the human dignity of a patient should be at the forefront for doctors.
