There is no standard answer to survival, because everything is relative to needs.
Raised in a desert area, water was always #1 on the list of things you need. But even that is mitigated if it is very cold out. You can freeze to death faster than you can die of dehydration.
While building a shelter is one thing, finding water where there is no surface water or snow is extremely hard. And even if you do, you need a container for it, or you are stuck at the water source.
It always made me laugh that porcupines were protected with the rationale that they are easy to catch and kill for food. Just peel it like an orange, I guess. Seriously, how do you butcher a porcupine? (Yes, it can be done, but they never teach that part.)
For a dropoff and pickup 24 hours is easy. Problem is in a real world stranded situation you need to think differently, you gotta either figure out where to go and keep yourself able to go there, or hunker down and make that survivable. Can’t do that. Luckily I’ll never need to, just don’t lead a life that involves the middle of nowhere.
24 HOURS IN A DAY?? 24 BEERS IN A CASE? I CAN MAKE IT.
I could probably do it but I wouldn’t like it.
My plan is (1) remain calm, (2) orient myself so that I know which way I'm facing, (3) make sure that my GPS unit has the datapack containing the nearest bars. If you're more than 24 hours away from the nearest bar, you probably shouldn't be there.
