He said "we don't really know why every time, Its partly genetic luck".
The key words are "every time" and "partly"

TLDR: Ten wild monkeys alone in a room with a big pile of Legos on a pillar will make a mess a lot faster than if the pile of Legos laid in a pit.
Evaporation: The molecules that the water is made of constantly bump into each other, sometimes these molecules get unlucky and get punched so hard, that they are thrown out into the air. Most don't get very far, however, since they run into the air molecules, which kindly kick them back into the water. Still, if the molecules get far enough away, the can catch a breeze and escape.
Boiling: The molecules in the water are much more violent at high temperatures. At some point, a hole with no molecules will form in the water. Since the molecules mosh so violently into this pit, they end up slamming into the sides of the pit violently enough, that it expands despite of the rest of the water pushing back. That is how bubbles form. The bubbles then rise to the surface, and push the air away with their energy and numbers.

Same. This is a game that'd benefit from a pirated copy going around for free. If I got to try it, and knew I really liked it like I think I would, I'd probably buy it...but for now, I have other games I've bought and haven't really played so I'm going to stick to those

My brother and I were walking down the Salt Lake City airport last week, and we commented that even though there’s a ton of people and the walkway is forever, it didn’t feel so bad because the ceilings were pretty high.

Reply to ELI5 why are snail tracks dotted? by RoddingRabbit
It's because they have only one foot. As they walk, or crawl or whatever, that dot is their foot print

Commoners didn't get to participate in the first place.

I also imagine people feel less claustrophobic with high ceilings. Airports can sometimes be packed

CJ says that at that exact moment, you can balance an egg on its end.

Reply to ELI5: Why do people get sun burnt/tan when sitting still, but don’t when they move? by Double-Emu7273
People get sunburned walking around or working in the sun.
It's just likely that moving around doesn't present any single part of your body to the sun constantly, and you probably move into shade intermittently.

People definitely get tanned while walking or running.
But more body coverage and overall even tan when ur laying down. You’ll notice people get more tanned shoulders and arms when just walking around.

I don't think that's quite right. The Earth is still tilted, just sideways with respect to the sun. So, for example, at the vernal equinox, the sun would just slightly to the north and set just slightly to the south

People do get just as tanned / burnt when moving. The people on the beach probably spent more time in the sun.

Water is just a bunch of molecules.
Imagine you have two friends who are identical twins (hydrogen atoms). You (an oxygen atom) stand between them and hold one of each of their hands (you are now a water molecule). You guys do everything together, and sometimes you’re tired and fall asleep, and sometimes you’re really active and running around like crazy, but you’re always holding hands. Now imagine there were millions , and millions of people exactly like you, all holding hands with identical twins - you’re all going about your lives, sometimes moving fast, sometimes moving slow. When it’s cold, like in winter – you’re more likely to stay at home, hang out with your friends inside, and not really do much. In the summer when it’s really warm outside, you guys are more energetic, and it’s way more likely that you go too far and too fast and lose track of the pack.
Imagine that you three, and a whole bunch of people exactly like you (other water molecules) were hanging out in a really big group, sometimes the threesomes that are moving really, really fast, and are on the edges of the group - lose track of everybody else, and end up separated. They just go off and do their own thing while the group continues on hanging out together.
That is exactly what happens with water. When water gets warmer, more “threesomes” are out running around and moving faster, therefore more of those “threesomes”, a.k.a. molecules get separated from the group, i.e. evaporate.
Now, when water gets to 100°C, it’s like every threesome in the group started moving that fast, and that energetically, that they are all equally likely to get separated and get lost - no Matter where in the group they are located – the group gets spread out further and further apart because everybody is running around so fast.
Basically, when a molecule leaves the pack – it evaporates. When every molecule in the pack is moving so fast that they are all equally likely to get separated, that is “boiling”. For water, that happens at 100°C.

Your first statement was too broad to be accurate. I tend to agree with the "impractical", yet it was specialized apparatus. As for the wiki quote, it doesn't prove the "set of stairs" and is only for a specific région and time.

Evaporation, in ELI5 terms, is simply a molecule of water getting so excited that it literally jumps out of the container in which it is stored.
A puddle of water contains a bunch of water molecules which are all bouncing against each other and their container, but they don't have the energy needed to actually bounce out of the container. Then a (relatively) warm room or a little bit of sunlight provides some extra energy, and a molecule gains the extra energy needed to leap out of the puddle and into the air.
This can happen at any temperature above O C.
At temperatures below 0 C, as described in other posts, water molecules can skip the liquid phase and go straight from ice to vapor in a process called sublimation.
It all boils down (pun absolutely intended) to energy input.

MOA does not use a central heating system; instead, 70 degrees is maintained year-round with passive solar energy from 1.2 miles of skylights and heat generated from lighting, store fixtures + body heat

Battle lances had a spear end, but tournament lances were very blunt and relatively large (the aim being to unseat your opponent from his horse, not kill him).
once one of the pair was inseated, usually the 'battle' would continue on foot, with blunted swords.
The aim was to get your opponent to submit, either by disarming him or just plain tiring him out. It didnt usually end in a simulated kill, like the movies show.

Being by water intensifies or reflects really, more light on people nearby.
