If you were being buried alive, why can't you just step up as the dirt is being added and stand on top of it? | If someone has just dug a grave, chances are they're not wearing flip flops.

Why I can easily accidentally fall asleep on the couch while doing something, but have trouble falling asleep at night in the dark & in my bed? | I'd guess because your mind starts working with lack of stimuli. Light stimulation works great for sleeping because you don't focus on all the stressors of the day or next day. I find it extremely useful to start my own dream as I'm getting comfy in bed. This provides some stimuli to keep my mind off of stress |
Can anyone with an intimate understanding of "Heuristic Availabilty" offer its basic guiding principle? is "seeing past events through the context of current understanding" accurate? | Not quite. I hope you're talking about the availability heuristic haha. Availability heuristic is basically just that we, as humans, tend to over confidently rely on information that comes to us easily.

How come you can hold your bladder for hours, but as soon as a toilet enters your vision it feels as though you’re going to explode? | Your brain is what's suppressing the urge to urinate when it knows that there's no chance of urinating at the time. Once you're near a toilet, the suppressing wears off, and you feel the full urge to urinate. You can think of it as a measure to ensure that you take the opportunity to urinate when you can. |
Climate Change - If CO2 levels were dramatically higher in history, why are we concerned with rising levels now? | Short answer: it's all about people. A hundred million years ago, it wouldn't matter if the sea level rose and most of Bangladesh was underwater. Today, if that happens, hundreds of millions of people lose their homes or lives, and that's just one example. |
