When a cell is damaged the body will try to repair or replace the cell to continue normal functions. If a cell dies the body will remove it and replace it with another functioning cell, or fill the gap with connective tissue to provide structural support for the remaining cells.
Note: The American's with Disabilities Act does not prevent payment of parking meter fees by an individual with a disability. Therefore, you should verify requirements of feeding parking meters and the time limit allowed in the jurisdiction you are visiting.
To legally use a handicapped parking spot, a motorist must have a state-issued placard, a permit valid for 30 days, or disability plates with attached emblems on both the front and rear of the vehicle.
