According to Nat, when she was just 15 she was forced to spend two months in a hospital bed to avoid being paralysed forever. "I got really sick with a disease in my spine called osteomyelitis," she revealed. "The bug had eaten two of my vertebrae and they were crumbling." "I'd had back pain and saw a physio who wrote to my doctor; I never saw what was in the note but that night I ended up in [the] hospital, [and] an orthopedic surgeon [told] me: 'Lie down, or you'll never sit up again.' "I didn't sit up again for months."
