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 have a Permanent Handicapped Parking Space State Permit (PHPSSP) which allows me to park in Handicapped Parking Spaces. 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.
