Not so long ago, my plan was to build a gameroom in the only free room left in our house: the attic (laughs in the audience).
I tried to bring a mildly heavy cab upstairs with a friend, first our spinal bones nearly exploded after less than 10 steps and then we distinctly heard the old wooden stairs going "CRRRRRRKKKK!". Lucky us, they didn't vertically collapsed (TM) though and we put the cab safely back in the entry hallway...
Later I thought that even if we had managed to bring a few cabs up there, the attic floor couldn't have stand it and the cabs would have ended up below in our bedroom. What a lovely way to die: crushed by an asteroids... there I would have had my 15 minutes of fame for sure!
