If my laptop screen were legible in direct sun, I'd be out there. Wifi and headphones.
Sadly the laptop's too small and Chrome's too power-hungry for solar power to be an option: ⅓m width * ¼m length * 158W/m2 solar = 13W out of 67W to run it, or 19%.
- itake 3y agoHow 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.
- cubefox 3y agoI wonder what stone age people did about skin cancer. Nothing, I assume.
- CubsFan1060 3y agoI don’t think they lived long enough for it to be a problem.
- cubefox 3y agoThey were a lot longer outside than modern people though.
- antisthenes 3y agoOutside != full sun. Sitting in tree shade won't give you skin cancer.
- insanitybit 3y agoHow 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?
- bawolff 3y agoStone 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 3y agoBro what - they did not use sunscreen - where did they get titanium and zinc?
- donkers 3y agoThe History of Sunscreen https://jamanetwork.com/journals/jamadermatology/article-abstract/2471534 https://jamanetwork.com/journals/jamadermatology/article-abs...
- armatav 3y agoAlso not seeing titanium, zinc, oxybenzone, octinoxate, octisalate, or avobenzone.
- haldujai 3y agoWho 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.
- armatav 3y agoPoint being that ancients did not use sunscreen or anything remotely close to the formulae we have today - what we have today was roughly defined 100 years ago and has some serious consequential effects on the endocrine system and more.
- haldujai 3y ago> Point being that ancients did not use sunscreen The statement being made by others is that "ancients" applied a topical substance to protect their skin from harmful effects of the sun, most would call that sunscreen[0] but use whatever word you prefer. > anything remotely close to the formulae we have today No one is making this claim.

- morsch 3y agoSkin 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. https://www.cancerresearchuk.org/health-professional/cancer-statistics/statistics-by-cancer-type/melanoma-skin-cancer/incidence https://www.cancerresearchuk.org/health-professional/cancer-...

- PartiallyTyped 3y agoCancer is a bigger problem now because we have learned how to deal with other diseases.
- wwtrv 3y agoWell yeah.. just like wild animals which break a leg, catch a serious diseases etc. they can't do anything about it and die.
- jimbokun 3y agoDon’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.
- screwturner68 3y agothey were dead by 40, skin cancer usually takes a little longer to show up and kill you.
- itake 3y agoHow long did Stone Age people live? I thought most people died at like 40? I’m planning on living longer than that.
- bowmessage 3y agoI feel like this is a VR headset's killer app - once the DPI gets there, it will let me bask in the sun while still being productive. I can't wait.
- osigurdson 3y agoI just set up on my deck with a deck umbrella and an external 32” monitor. It works well but it would actually be nice to have polarized glasses that improve the situation instead of making it worse.
