On the US Military combat uniforms, where the flag is put on the sleeve of the uniform, the flag patch is displayed with the stars facing forward, in the direction the wearer is facing. This is done to give the impression of the flag flowing in the wind while being carried forward across the battlefield. This is known as the "Reverse Field Flag."

That math checks out. Keep in mind that most major health organizations are saying something like this about the safe levels of total daily intake:
Intakes up to 400mg per day (about 5.7mg/kg bw per day) consumed throughout the day do not raise safety concerns for healthy adults in the general population>
Not saying you should change what you're doing, just putting it out there for everyone
You might want to look up "half life of caffeine" before you spend all day drinking like that. Your body metabolizes caffeine differently than alcohol.
Alcohol is linier e.g. 1oz/hr. Caffeine is halfed every ~5 hours. So if you start at 100mg, 5 hours later you're going to have 50mg still going, 10 hours down the road you have 25mg. Fun times if you have 4 cups of coffee over a two hour period at 90mg a cup you're going to have ~350mg and it's going to take ~20 hours to get under 25mg.
There are numerous apps to track the actual amount of caffeine in your system at any given time and you might be surprised at how high the numbers go if you haven't tracked it before.
In the US this is different in each municipality, with the majority not allowing it. Many places that do allow it also do not allow glass, only plastic cups or cans.
Fun fact; cats can drink straight seawater. Mad good kidneys or something, so the soup is going to get far too salty for a human before it gets too salty for a cat.
Having had to work with people, manage people, hire and fire people. I would say that having a higher education does not equate to a persons level of smartness, knowledge, or intelligence in any reasonable way.
This is due to the possibility that the lithium battery could be crushed, say in a seat recline mechanism, and catch on fire. Your modern small black rectangles are actually quite dangerous in a confined space.
