Of course, prevention is better, and I would like to acknowledge the New Zealand Dermatological Society, who recommended minimising time in the sun, particularly when it's most intense; seeking shade; and wearing a broad-brimmed hat, wraparound UV protective sunglasses, and high ultra-protective clothing covering most of the skin. That is not how most New Zealanders spend the summer, and we try really hard just to get our kids to do that.
