While yoga and an ascetic lifestyle keep Prime Minister Narendra Modi sprightly through his work, the 64-year-old's healthy routine has also provided relief to four doctors who accompany him on his travels.
One of the four members of the medical team told Hindustan Times the PM's lifestyle choices -- doing yoga regularly, a vegetarian diet, abstaining from alcohol and tobacco -- have ensured he enjoys a health status better than many younger to him.
"There are only minor age-related issues," the doctor, who wished to remain anonymous as he was not authorised to speak to the media, said.
The Prime Minister's medical team includes a personal physician, a critical care specialist, a surgeon and a paramedic. The team travels heavy, carrying along an array of medical equipment including a defibrillator, an infusion pump and a portable suction machine.
The heavy equipment is packed in around eight bags, the doctor said.
The team is usually recruited from among top practitioners from hospitals such as the All India Institute of Medical Sciences, Ram Manohar Lohia Hospital and Lady Hardinge Medical College -- all Delhi hospitals.
At 64, the PM is one of the older members of his cabinet but his day begins early -- at 5am -- with a cup of tea followed by pranayama (an alternate breathing technique) and some yoga.
Barring two 30-minute breaks for lunch and dinner, PM Modi works late into the night and ends the day around midnight.
Manmohan Singh, the previous prime minister, was known to give a lot more trouble to his physicians. Not only did he undergo two bypass surgeries, he also suffered from a prostrate problem and diabetes.
