The process you’re thinking of is oxygenation, not oxidation. Oxygenation is the binding of oxygen to other molecules, oxidation is the loss of electrons. When the iron in hemoglobin oxidizes (from Fe2+ to Fe3+) it stops binding with oxygen, and if it oxidizes further (to Fe4+) it can start oxidizing other molecules in your body. Your body has enzymes to reduce the iron back to a reactive state, but antioxidants also play a role in reducing oxidized molecules.

There isn’t a grain elevator on every farm, farmers transport grain to them on trucks. So yeah, passenger rail as frequent as grain elevators would be great. Still need cars to get there.

If you actually have a reason to live out there, like a farm

maybe car brains should all just get the fucking wall

I’m not going to bother here.

He’s literally going to The Hague for a NATO summit. Chill.

Immunotherapy for allergies uses literally microscopic doses of allergens to avoid triggering a reaction. It’s not really possible to consume an amount small enough to get the same effect.

Depends on the severity of the allergy. Sometimes epipens are prescribed for people who have a risk of anaphylaxis but have never actually experienced it. Which means that people doing this are still tremendously stupid, but not unbelievable.

And people drive themselves on those roads. You need to hire people to run and maintain the trains.

How far do you expect people to walk? The rural parts of my state have an average of less than 10 people per square mile. Is the train stopping every mile or two? Not terribly efficient. Trains between and around population centers would be great, but expecting rural people to fully ditch cars is just completely infeasible.

Right, because it’s totally feasible to run a personal rail line to every home in a rural community. Taxpayers will happily pay for miles of rail so one family can get to town.
