fleshing the knuckle of the conversation that started with, "The bridge, by me is ****** with ice"
Caution is a boomerang, that, once thrown- may disappear for years- but it will return, and return hard-  
For me, it's in my early 50's- approaching a decking bridge, slick with ice, reaching into my pocket  and thinking "****!, where did that boomerang come from?"

I crossed the bridge- it was pathetic- thank the Lord and all his bearded chums, it was dark...
