Stop in for a cup of coffee

Question for you all....

Why do I worry about the engine for Bonneville running high rpm for 5 miles when I don't give it a second thought to run an engine at work right now at 5500 for 30min? Or last Thursday at 5500 for 3hrs? Or years past at 6200 for 12hrs straight? Shouldn't I be numb to it?
i worry bout 5 seconds over 5500.... i see everything in life as the worst case scenario and expect **** to go wrong.. it's a **** way to live.

P.S. you prolly worry less at work cause you don't pay for it if it blows up :)
