Thank you for the public service announcement, which I plan to share with my sons. My wife's heritage is predominantly Scots-Irish, and mine is Scots-English, with freckles to prove it. I am extremely uncomfortable in strong sunlight, which is probably a protective reaction, and I tend to do most of my cycling, walking, and running early or late in the day, and always with some sort of head covering. When I work outdoors on the house or landscaping, I schedule my work according to where the shade is.

The threat of melanoma and other skin cancers increased radically with the hole in the ozone layer, which fortunately has been gradually healing. There was an even bigger pandemic of skin cancer in Australia than here.
