Paranoia ? How many holds have broken on you ?
A lot. One day I was climbing a flake. probably a first ascent, 5.9 5.10 who care, and at the top, the flake was so thin that I was able to broke it in my hand. I protect lower and did the move to the right...and a large block, three by two, came loose and felt. My partner was not in the line...as we are supposed in trad ethic, and we were safe. In an other place, some block came loose and I drop it close to my belayer. He was afraid and jump directly in the middle of the falling path...pulling on the lead rope...the stretch of the rope save me. In the yos, there was a kind of needle of rock. I place my foot on it even if it was moving and make the move. In duet, I want to a traverse and I saw a small loose block. I removed it and place it on the side...try to do the move and replace the piece of rock and used it as a hold. There is many other when you climb in remote area.
I think that I learned how to place my body to not be hurt when I was doing aid climbing. When you aid, you have time to see the danger, decide how you want to fall and if your protection, under you, is going to hold.
One day I asked to a sport climber if he ever did aid climbing: he said Yes, I climbed in a gym!!!they help me a lot
