  • 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.

    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.







  • To be fair, ADHD is a developmental disorder that sometimes can present as delayed development rather than halted development. I.e being behind in executive functioning development but eventually “catching up” to peers.

    That said, the severity of cases is still often determined through the lens of “how well do they fit in/mask it” and not “how is their emotional/mental wellbeing”, which definitely gives the impression of kids “growing out of it”.





  • Neither 110VAC or 240VAC is inherently more dangerous as long as the system is paired with the right gauge of wire. As for personal safety, both are more than capable of killing you regardless of amperage. 240VAC may even be a little more capable because it can push more current through the resistance of your body.

    I’ll admit, American plugs/outlets leave a lot to be desired, but it’s not any more dangerous because of the higher current.
