Ndhlovu grew up miles from the coast, in Soweto, outside central Johannesburg. In 2016, on the heels of a divorce, she quit her corporate job and flew to Bali where she learnt to snorkel and then scuba dive, before taking up freediving back in South Africa. It wasn't without difficulty – to dive beyond 23m, she had to let go of fears and learn to be present. With freediving, she says, "the journey is so inside".
