It seems as though nothing can stop Mary Jackson.
The Weymouth, Massachusetts, woman, who will turn 100 on Aug. 7, has won three more gold medals in the backstroke as the first centenarian to compete in swimming at the recent National Senior Games, according to The Patriot Ledger.
Jackson began competing in the backstroke at age 91 in state and national senior events. She has a total of 24 gold medals.
