Bloodletting is still a legitimate medical treatment, now called therapeutic phlebotomy.
Some medicines, like testosterone, can increase your hemoglobin or blood count, so donating blood is the fix for it.

Ethanol can help protect your liver from the damage an acetaminophen overdose causes.
You'd think that doubling up on liver harming substances would have an additive effect, but nope.
There are over 100 volcanos on Antarctica
You can see where the pacific ocean meets the atlanic ocean
people still believe the moon landing/launches are all cgi made up even to this day, seems very prominent amongst older asians believing in this conspiracy.
If you're not familiar with the flavors of quarks, they probably seem fake.
- Up
- Down
- Top
- Bottom
- Charm
- Strange
Of course they all have antimatter counterparts. But anti-up is not the same as a down quark, anti-top is not the same as a bottom quark, etc.
For one hour each year, part of Florida and part of Oregon have the exact same time on their clocks.
Sharks have existed long enough as a species to have orbited the entire Milky Way Galaxy - twice.
I don't understand the clock one.
The shark fact is impressive though. I like to tell folks that the galaxy is so big that the solar system hasn't even made 1/4 of an orbit since the non-avian dinosaurs went extinct. Might add some perspective.
Nitpick: there are many speciea of shark so maybe you meant taxonomic genus or family.
I don't understand the clock one.
Part of the western Florida panhandle (WFP) is on Central time. Part of southeastern Oregon (SEO) is on Mountain time. That puts them one hour apart.
In the fall, when we go back into Standard Time, when the clock hits 2am, you flip the clock back to 1am.
So, during a normal night, WFP would be at 2am and SEO would be 1am. But on the night the time changes, WFP hits 2am and immediately flips their clocks back to 1am - which means that, for one hour a year (until SEO hits 2am and flips their clocks back), part of Florida and part of Oregon's clocks are showing the exact same time.
I kinda struggled over how to word this - they're not in the same time zone, but for this one hour they might as well be.
Trigger Warning: Existential Crisis
~~Everything about us is young in the context of the wider universe. Human society, the human species, the planet earth, our solar system, our sun. We live near the dawn of creation, even though our universe feels unimaginably old compared to our brief lives. As the skies darken and all the stars burn out, that will take course over a time period longer than our individual solar system will last. When the last light goes out, time doesn't stop, no the universe goes on and there's an even longer period of endless empty inky blackness, the deep void. In the end, the universe may spend significantly more time as an endless dead void than it ever did as a universe with hope of life and at least one planet with confirmed organic life. There is no escaping it, and there is probably no way for our species to even survive and adapt to that era as it is.~~
One of the possible answers to the Fermi Paradox is simply we're the first.
Time being a physical dimension in spacetime that can stretch and squish and 'now' isn't the same for every observer is probably the least intuitive one I know
If you rub two creatures together just right you get another creature of mostly the same type a little bit later.
Some fun geography one's.
Maine is the closest US state to Africa.
Alaska is the northern most, Western most, and Eastern most state in the US.
The Kings Chamber in the great pyramid of Egypt maintains an average temperature of 68°F (20°C).
I don't know, that seems kind of right to me.
