There's no telling when will be your last day, or the events leading up to those final hours.
32-year-old Rajesh Maru was completely healthy the day he went to visit his elderly relative at a hospital, but he was the one who would never walk out those doors again.
Magnetic resonance imaging (MRI) machines use a powerful magnetic field to capture images of internal body structures. For that reason, metallic objects can easily be pulled towards it and must not be carried into the room.
In 2001, a six-year-old boy undergoing an MRI scan in New York was killed when a metal oxygen tank flew towards the machine and crushed his skull.
Maru, from Mumbia, India, was the "sole breadwinner" of his family. He was working hard as a salesman to make ends meet.
In the hopes of helping his sister's mother-in-law, who suffered from a viral fever, at Nair Hospital, he was asked to carry an oxygen cylinder by a junior staff member, who assured him that the machine was switched off.
But that was far from the truth...
