When Zev Rosenberg hit his head while working at his HVAC business in 2015 and lost feeling throughout his body, his first reaction wasnt panic it was calm calculation about how long it would take for someone to find him.

It was about 2:00 p.m. If my wife hadnt heard from me by 5:00, shed probably start to worry a bit, but she wouldnt want to bother me, so she probably wouldnt call anyone until 6:00 or 7:00, he recalled. I was like, I could be here for a couple hours, so buckle up.

Its perhaps not your typical response to paralyzation from the neck down, but Rosenberg isnt your typical guy. The 57-year-old, who suffered a spinal cord injury that temporarily paralyzed him and made him an incomplete quadriplegic, ran a marathon just a year after his injury and will run the Pittsburgh Marathon on May 5 to honor the 11 people killed in the Tree of Life synagogue shooting in 2018.
