When I developed a clenching habit, I resolved it by training myself to put my tongue in the correct position in my mouth. It is pretty simple: with your lips closed but your teeth not touching, place the tip of your tongue right where your gums and your two top front teeth meet. That's it. At first it takes effort but once the habit and muscle memory develops it'll happen naturally. This eliminated my bruxism because now my jaw has a healthy resting state.
The thought of humanity destroying the environment to get the oil and then, in a fit of panic and at great expense, pumping it back into the ground, caused me to erupt in laughter.
Thanks for the straw man. American WW2 mobilization didn't kill ten million people - that's not an intrinsic attribute of a country focusing on something.
Think also new deal / public works projects like the Hoover Dam (many died working on the Dam but not because it was a government mobilization project). Just the government spending a bunch of money on environmentally focused projects could happen and could be good.
Are you against this? Flexible working hours that can bend to accommodate very malleable human lives seems better than rigid adherence to traditional schedules for the sake of it.
Different universities work differently in the US. Some have categories of majors, like UW [0], where some are free to declare but others have requirements/prerequisites.
