In the south we have an other way to deal with sun than people in the north.

And always the causes for a cancer are multifactorial. 
It's not just the sugar and potatoes.
And large exposure to sunlight in midday hours is bad for your skin, that's why you use sun cream. It's a fact 🔥
If you don't use it, it burns your skin, ask your mother, or even better...
Don't trust me, verify it 😜

And having your skin burnt should anything good for preventing cancer skin... but who knows! 

 I agree that cancer is a complicated disease but it is 95% environmental, and it is epigentical rather than genetic.
Unfortunately sunblock creams are carcinogenic.  As a fair-skinned human it is best to limit direct sun exposure, cover up with hats & shirts, and of course adopt a more saturated fatty animal based diet and avoid seed oils. 

 Sure! Best way it's to avoid direct sunlight exporsure the more the better. Totally agree. 

I was just pointing that he was probably using suncream but posting that sun it'd not bad for skin 🙃
