Intriguing. I’m on the water windsurfing and foiling quite a bit. Been wising up and using that ProTekt stick. Nearly every old timer has had their face scooped out at some point. Gnarly
"For every death caused by diseases related to excessive sun exposure — such as melanoma, the deadliest form of skin cancer — there are 328 deaths caused by diseases of sunlight deprivation"
Upon listening to this podcast a couple of years ago, I did go out and buy "Embrace the Sun". It gets a little repetitive throwing research and statistics at you, but it is important information regarding using the SUN to help gain optimum health...and perhaps eliminate lingering ailments or chronic conditions.
I DO use a zinc oxide sunscreen, with a fairly clean ingredient list, if I'm going to be out in the sun more than 3+ hours...and I'm often out there 5-6 hours as a tennis teaching pro. In those cases, I'll also wear a wide brim hat with SPF protection as well as long sleeves. Otherwise, I go unprotected...and never burn.

Discussion
One - it would be interesting to find out if they were using sunscreen - which actually leads to more cancerous outcomes (studies quoted repeatedly in the Embrace the Sun).
Secondly, the incidence of cancer still exists for people that get ample, unprotected sun exposure...but less incidence of the life-threatening melanomas. There is also ongoing research to tie the use of seed oils to incidence of cancer "caused" by sun exposure.
