Is Ignorance Bliss?

Like a cracked and weathered road that's replaced by a three lane highway, my life has lost itself somewhere within the wrinkles of time. My smiles are rarely forced (which is exceptional by the standards of national surveys) and I have little to nothing to bitch about.
It's all just become a touch surreal. It's as if I'm awaiting the pinch that will awaken me from a coma induced slumber. As if I was in a car crash as a younger lad and thrown unconscious and away into a equally plausible stream of events called life. I can see it now. I'd be awaken at that prime High School age, only to let all of this life fade from my memory as if it was a dream that I could swear I'll remember as I awake, although barely remember the synopsis of after my morning shower.
Funny thing, diagnosis. Especially towards yourself.
Some people put "No Trespassing: Prosecutors will be SHOT on sight!" signs upon their property. At worse, you'll be shot. Might die, might not. Most of that depends on circumstances such as the range of the shooter, how close a hospital is, and possibly wind direction. It's too bad life doesn't have such abrupt warnings.
"Don't go to that school, it ain't worth the money!"
"Don't go to the bar and take shots... it's gonna hurt in the morning and you're gonna feel like a fool!"
You get the gist.
Then again, the signs are always there. We just ignore them.
