4/ “Get sun like our ancestors” is meaningless without asking whose. Pigment evolved to match local UV. A Fitzpatrick II and a Fitzpatrick V have totally different optimal — and maximum — doses. Stop copy-pasting one tan protocol onto every skin type.
There’s been a lot of debate about the Sun lately. On the left we have Dr Paul Saladino(age 48), a proponent of sun exposure even in the Fitzpatrick 1 types. On the right we have Bryan Johnson(also age 48), who encourages limiting sun to early morning(UV index 3 and below). Which looks better?

3/ The part they always skip: the dose isn’t universal. More melanin (higher Fitzpatrick) = you need more sun for the same vitamin D, and tolerate more before damage. Fair skin needs less and burns faster. One prescription for everyone is the tell they’re not serious.
1/ Every sun benefit people cite — vitamin D, circadian rhythm, mood, nitric oxide — saturates at LOW doses. You don’t need to bake to get any of them. Past the saturation point, extra UV is just damage with zero added benefit.
@Hardymatt0 I’ve had experience with a tribal minded person like this. Their “truth” is anything that serves them. It isn’t a universal adherence for them. This mentality is incredibly dangerous to the sanctity of universal truth.
So, Netanyahu is now openly boasting to the world he doesn’t care what the President of the United States thinks or says. Over to you, Mr President @realDonaldTrump - who’s the boss?
