I wonder if bungee jumping was invented when someone was tied to a rope in case they fell off they could have been retrieved. On another note, I am a recovering alcoholic and before I quit drinking 40 years ago, I used to walk crane I-beam when someone would not have crane over load and trying to pick slightly out of reach of the trolley in 30 foot ceiling. After I got sober. I could not do it anymore. Like Frank said "age and wisdom" now prevail although at 73 I am grateful to still be fairly active.
