My great-aunt Bea was mugged, or at least someone about that age attempted to mug her, when she was in her nineties, about 93 if I remember correctly. She was living in New York City at the time, and someone tried a snatch-&-run. She held onto her purse, whacked him over the head with her umbrella knocking him down (I think with surprise as much as anything) and SAT on him till the cops came. Went to testify and everything. Lived to be 100 and a half... those indestructible Quakers! Sorry this kind of thing has crossed the pond...
