Prince Charles, 71, as a senior royal, however, does take a Royal Navy doctor with him when he travels, as well as a supply of his own blood.
This is most likely to be the case at the moment as he visits New Zealand alongside wife Camilla, Duchess of Cornwall, 72.
Earlier today, Camilla and Charles completed their second day of a jam-packed royal tour to New Zealand – their third official visit together to the country.
The pair received a warm welcome at Government House, where they received a traditional Maori greeting – rubbing noses and placing a dart on the ground for Charles to pick up.
