After the catastrophic issues of the Earth's spin suddenly stopping have settled, then yes, one side would become desert hot and the other would be an ice age. Life would only survive between the two sides, to varying degrees, based off how far away you were from the border.

Think about summer and winter as it is now, the extremes of "seasons" that earth currently has is purely based off how far away you are from the equator during specific times of the year. The equator is always warm because it's exposed to the sun on average more than any other part of the world. The further north or south you go the temperature varies in magnitudes higher. All because the Earth's tilt let's you see less or more sunlight/heat radiation in a day.

It's not like it's written down anywhere but I'm pretty sure it is. It might not be acceptable in the sense that people wish it didn't happen, but I think it's acknowledged that it does and will always happen.

Good note about the chlorine smell though, now I know I'm definitely not the only one who also pees in bodies of water.

As someone that was on a swim team, you're only getting out to poop.

Bro maybe suggest that then. I definitely did not get that from your title.

Not over a fireplace

For me last two homes I've had this situation (mounting tv over fireplace) where the studs are not placed apart normally. Pretty easy to get around, just get a board to mount to the studs then mount goes on board
