i just figured out what it is. its really just 'paying full attention.'

i but a brake on my bike and now im a reckless moron. im crushing the hell out of my gear even when lights are red and traffic will not allow. im only skidding to scrub speed now but im threshold braking so hard im like a unicycle. i swear to god i was probably safer without.
anyone ever put a brake on and feel this way?
