Krishna, who normally maintains perfect health and fitness, has never complained of any sickness. He is even contemplating returning to active politics by joining YSR Congress party. However, of late, he has not been keeping good health. After all, he is nearing 70 years! Krishna’s wife Vijayanirmala was on his bedside at the time of operation. Mahesh Babu is likely to cancel his shooting to return to Hyderabad to call on the father, sources said.
