How do you factor in skin cancer with this mindset?

While I love being outside, I always wear hats, hoods and jackets to protect my skin.

Also cataracts would also be a problem.

I wonder what stone age people did about skin cancer. Nothing, I assume.

[morsch]

Skin cancer is one of the more relatively common cancers in young people, but first diagnosis still increases sharply with age. Life expectancy at age 15 (so, without the 60% infant/child mortality) in the Paleolithic was apparently 54 years.

Don’t know about Stone Age, but look at the clothing worn by desert tribes. Loose fitting clothes covering arms and legs, so e kind of covering on the head.

I think the dangers of over exposure to the sun have long been known and only recent generations think shorts and T shirts in direct sun for long amounts of time is a good idea.

Stone age people used sunscreen. It wasn't anywhere near as effective as modern sunscreen. Presumably they were less concerned about skin cancer and more concerned about the immediate effects of a sunburn

[armatav]

Bro what - they did not use sunscreen - where did they get titanium and zinc?

Also not seeing titanium, zinc, oxybenzone, octinoxate, octisalate, or avobenzone.

[haldujai]

Who is defining the word "sunscreen" so narrowly to these compounds?

All you are doing is listing modern formulations, some of which are not even generally regarded as safe anymore.

That’s not our sunscreen.

[CubsFan1060]

I don’t think they lived long enough for it to be a problem.

[cubefox]

They were a lot longer outside than modern people though.

[antisthenes]

Outside != full sun.

Sitting in tree shade won't give you skin cancer.

[insanitybit]

How much UVA/UVB gets filtered out from shade under a tree? And how much vitamin D are we getting to make sitting in the shade worthwhile?

[wwtrv]

Well yeah.. just like wild animals which break a leg, catch a serious diseases etc. they can't do anything about it and die.

[itake]

How long did Stone Age people live? I thought most people died at like 40? I’m planning on living longer than that.

[PartiallyTyped]

Cancer is a bigger problem now because we have learned how to deal with other diseases.

[screwturner68]

they were dead by 40, skin cancer usually takes a little longer to show up and kill you.
