I came to leave a snarky joke comment about "in mice?", and then I remembered that mice don't actually need parachutes because their terminal velocity is roughly the same as a human using a parachute [1]. If someone actually ran the study with mice, they'd find that parachutes aren't necessary! 1: https://johnmjennings.com/can-a-mouse-survive-a-fall-from-a-...
But what's the terminal velocity of a parachute backpack strapped to a mouse?

The fact that mice don't appear to deliberately jump off high things as a way to get down tells me that they probably do get hurt... Just because they don't fall super fast doesn't mean they don't get injured because they don't have as much distance to "drop and roll" like a human does.
> The fact that mice don't appear to deliberately jump off high things as a way to get down tells me that they probably do get hurt... They explicitly added the caveat about the soft ground. There'd be very little opportunity for mouses to become comfortable with jumping from high areas as there'd be very few occasions that satisfy the requirement. If the mouse jumped into a cave and can't get out, it'd starve to dea…

#73> Only two options exist. The first is that we accept that, under exceptional circumstances, common sense might be applied when considering the potential risks and benefits of interventions. The second is that we continue our quest for the holy grail of exclusively evidence based interventions and preclude parachute use outside the context of a properly conducted trial. Both options may be true for different cases. I…
That's option one. Or do you insist on some particular definition of exceptional circumstances?

It could be to avoid getting disorientated though, or to be able to see a predator and reverse course...

I have a vague recollection of reading that most squirrels have evidence of trauma from falling, such as healed bone fractures.

#79How do we really know whether double blind randomized controlled trials actually work? Is there any RCT done on evaluating the efficacy of RCT?
