I spent 21 years in the military
Thank you for your service. Sincerely.
It is still my opinion that you are foolishly risking your hearing and sight, and I wouldn't be much of a person if I ducked and covered concerning this conviction. You may wish to acclimate yourself to various emergency conditions and it is your prerogative to do that as you see fit.
Hearing and eyesight protects your life and limb during normal mundane everyday situations- as well as stressful ones- by letting you hear that bus, or see that fan blade. It is not as sexy as preparing for a gunfight, but getting run down by a taxicab gets you just as dead as a .40 to the heart. Please think about it
