Rod Stewart has little hesitation when it comes to diving in on solving something. Some months back, the 78 year old rocker took it upon himself to repair potholes on the street near his some. This past week, he did another good deed. After learning of delays at a nearby hospital for MRI procedures due to advance payment paperwork processing, Stewart went to the Princess Alexandra Hospital in Essex, UK Friday to let them know he would cover the costs of the procedure for 20 patients to speed up access to them for others. He has also indicated a willingness to foot the bill to reduce wait times at other hospitals.
