Right now I use Read You on my phone to get RSS feeds and I read articles on my browser but I want to cut the time I stare at my phone throughout the day so I came up with this system:

Once a week I will look at all the feeds I follow on my PC RSS reader, select the ones I want to read during the next week and save them / export them (possibly in PDF or ePUB?) so that I can put them on my old Kindle (that has no internet access) and read them only using the kindle during the week.

This will drastically reduce the time I use my phone to first scroll and select articles and then to actually read them. Looking at a screen all day for work and also looking at a screen (phone) in my free time is not good for me and I want to change that.

If no RSS reader has that option, does anyone know of another program or firefox extension that would let me "export" web pages as pdfs or epubs?

I'll start with: medical conditions, everyone would prefer to have an average well known and curable disease than a special case or a unique one

First of all, I know this is not the kind of questions that usually are done in asklemmy but I don't know where to ask, sorry folks.

It's a 5th generation kindle and I really loved reading on it. :(

Bonus question if the kindle is doomed: best e-ink reader on the cheaper side? I don't want anything super powerful or fancy, I just want to load my collection with calibre and read on it. - bonus points if it's a libre and or open source friendly.

4 ways of using it come to my mind:

• Place hands on the inclined outer handles and do a pull up with arms open wide
• Place hands with palms facing the wall on the "inner" handles and do a pull up with arms at shoulder width
• Place hands with palms facing my face on the "inner" handles and do a chin up
• Place hand on the handles which point out of the wall and do a pull up / chin up (sorry don't know in this case)

Are these excercises different for the group of muscles they target? And if so, how? Is there any ranking among them from worse to better?

Also if I can do chin ups just fine but I can only do negative pull ups, which ones should I choose?

I'm referring to the human race evolving in the African continent and then migrating to the rest of the world.

Evolving in Europe made people light skinned to account for the reduction in sunlight exposure, are there any other traits which other ethnicities developed to adapt to their new environment? Or are the diifferent traits in different ethnicities just stuff that developed by chance and got somehow reinforced because of the isolation between populations?

This question came to my mind first thinking about "Asian eyes", do they serve any "purpose"?

Alternative title: Dinosaurs wouldn't be that big if they weren't that big

Any topic, just explain what it is please

I know evolution is governed by chance and it is random but does it make sense to "ruin" sleep if there's light? I mean normally, outside, you never have pure darkness, there are the moon and stars even at night. In certain zones of the Earth we also have long periods of no sunshine and long periods of only sunshine.

I don't know if my question is clear enough but I hope so.

Bonus question: are animals subject to the same contribution of light or lack of it to the quality of sleep?
