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.
DDOT says that free parking at metered spaces has become a prime incentive for drivers to use fraudulent handicapped placards or plates. Drivers with legal handicapped placards or plates will have to pay the normal rate at non-handicap meters. Fines for illegally parking in the spaces will begin after a grace period that ends March 1.
