Polluting with what? It's mostly stainless steel and other inert materials.

I don't think we have any active craft capable of recovering it. The space shuttle probably could have done it, but with a cost of about $1.5b per launch, there is no way that would be worth it.

SpaceX's Dragon 2 easily has enough cargo capacity to bring it down (~3 tons vs 0.5 ton), but there's still the question of intercepting, capturing, and securing it in Dragon's cargo bay. That would still cost something north of $100m to recover the lander.

In space, assuming you're not too far out, heat is abundant. Literally just put the ice in an insulated room with a window facing the sun. If you want to get fancy, use mirrors to focus the sunlight.

There is no "right" choice. Both choices immediately end the "game". It's just a short story with two endings.

Try OTC reflux medicine like Prilosec (Omeprazole). Works way better than Tums for reflux in my experience.

This sounds like the same cycle I go through, especially the forgetting part. I've found that cycling caffeine through the week (taking a break on weekends) and just not having too much even during the week can help maintain the productivity, but it also means spending my weekends in a tired daze. I think I just need to commit to not having any caffeine, or if I do, only taking it temporarily before stopping again.

Any mechanism that could switch the magnet on and off would require energy. E.g. you could put a magnet next to it with opposite poles, which would mostly cancel out the magnetic field, but would require a lot of force to push them together, which is work, and thus requires energy.

There are a few games where the point is basically to write a bot to play for you. Off the top of my head are Screeps and Adventure Land
