Indeed. People who don't do these kinds of activity wildly overestimate their physical capabilities. Part of the reason for this, I think, is that Hollywood and TV depicts ludicrous levels of acrobatic and athletic capability as the norm; apparently normal people in movies are depicted catching falling people one-handed, outrunning explosions, and so on. Climbing, even at an enthusiastic amateur level, is much harder than non-climbers believe, and I think your suggestion that readers try top-roping a 5.9/5.10 to get some idea of even beginning climbing difficulty is an excellent idea. I cannot even imagine the level of dedication and expertise it takes to do this sort of feat.
