post demonstrates an absurd level of ignorance I've never come across before, even on the internet.
Firemen retire when they are around 50 years old because by then they are either dying from asbestos-caused cancer, or are so crippled from falling through burning buildings onto cement basement floors that they can barely walk from the constant pain. How does this happen, you say? Because they were trying to save your worthless ass, that's how.
Policemen retire when they are around 50 years old because by then they are either on the edge of insanity or about ready to eat their gun from seeing man's inhumanity to man each and every day of their lives and not being able to do much about it. How does this happen, you say? Because they were trying to save your worthless ass, that's how.
Military Servicemen retire when they are around 50 years old because if they weren't killed or crippled in war they are usually dying by then from some horrible substance they were exposed to by their own government without their knowledge. How does this happen, you say? Because they were trying to save your worthless ass, that's how.
Firemen become Firemen because they know someone has to pull babies out of burning buildings and they feel up to the task.
Policemen become Policemen because they know some people need to be controlled and they feel up to the task.
Military Servicemen enlist because they know there are evil regimes that need to be held in check and they feel up to the task.
The common thread is all 3 ended up needing to retire at 50 because they risked their lives trying to save your worthless ass.
Makes me wonder what, if anything, you've ever risked for someone else?
