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.
I do not have to pay a parking meter and I get to park for free. You should contact the local police and ask about Handicapped Parking laws. The police should be able to give you information since they are required by law to enforce Handicapped Parking laws.
