It was Monday morning Aug 25th in Houston Texas, time to infuse his patient's immune cells back into his body so they could kill the melanoma tumors threatening his life.

But the entrance to Dr. Adi Diab's apartment parking garage in Houston was blocked by water from Hurricane Harvey's floods and he couldn't get out that way. The timing of patient John Cormier's treatment was crucial he was sitting in a hospital bed, his immune system deliberately destroyed by chemotherapy, and the replacement cells wouldn't last long in the lab. So Dr. Diab put on his only boots and waded three miles in water to MD Anderson Cancer Center to hopefully get there in time to start the treatment.

When this patient thinks of a defining moment in his life 40 years a from now, it will be his Dr, Adi Diab from MD Anderson with the backdrop of the Hurricane Harvey and flooding streets.
