Lemmy ask something: What specific set of tasks would you perform if you are informed that a world-ending event is about to take place (e.g. nuclear war, comet impact, alien invasion etc.)

Drink all the alcohol and smoke all the weed. I don't want to feel it when it happens. Just let God take me back.

Not much, just vibe.

If we had a lot of warning I'd probably browse/share memes of it happening.

Boot Up Fallout better get som practice in before the nuke hits..

Imma get baked AF, hugged my loved ones and pets, send goodbye messages to my far flung friends, bend over and kiss my ass goodbye.

Depends on how much advance notice. Anything under a day or two I would just spend time with my wife, reminiscing about our life together eating and drinking what we love.

If it's weeks I would (re) connect with friends and family, tell them how much I appreciated them being part of my life and, if needed, straighten out misunderstandings so I'll be ready to face the end with a clean a slate as possible.

Thinking about living conditions over the end period, days or months would probably be no big deal. Days - nobody has any time to do anything or just shock. Months and half the population wouldn't believe it or would go on as if nothing were to happen.

If it were weeks, though - that's a tough one. I would probably hoard a bit then seek out a common meeting point for family to converge. Look at the comments here - everyone is tapping out. The reality is that a duration of weeks (say, 2-4) is short enough that certainty is high so most people would believe it, and just long enough that the entire fabric of society would break down - distribution networks, transportation, police, services. We saw how things went to hell in a handbasket when the first lockdowns for Covid hit. Trash will pile up. Store shelves will empty. Any service requiring human interaction to run - trash, power, water, sewer, public transportation - probably left without operators, probably not shut down gracefully.

I've actually had a minor 3am panic /nightmare about this - if the shit hit the fan, would I have enough gasoline in my vehicle to pick up my daughter at school and bring her home? (college student, 300mi away).

Myself: will probably panic and start thinking what I should do next, until the disaster hits.

Call the loved ones and pray!
