As part of Georgina Harwood’s 100th birthday celebration, she went on a great white shark dive off Gansbai, South Africa, yesterday. In addition to the shark dive, Harwood also celebrated turning 100 with a skydive two days earlier. Harwood, a great-grandmother, began skydiving when she was 92, but this was her first shark dive.

Her recent skydive was done, in part, to help raise money to buy life-jackets for volunteers at South Africa’s National Sea Rescue Institute, according to a HuffPost UK article.
