Some articles about microfractures:
We dropped 30 carabiners from heights of 21, 40, and 109 feet onto concrete, filmed the impact on high-speed video, and tested their ultimate strength. ... There was no difference in breaking strength between brand new carabiners and ones that had been dropped, even from 110 feet.
I'm going to go out on a limb and give a sort of non-TGO answer because it seems like you already know the answer and this is more psychological.

Clothing (Taking a jacket on and off
