I am only 21, but seem to remember things being quit different when I ws growing up:
I did a report on going shooting over the summer, and taped shell casings to it, and DIDN'T get expelled under some zero tolarence policy. 
 
I can remember bringing a pocket knife to school on a few occasions, teachers knowing about, and nothing happening about it.  
 
I sed to climb trees, walls, fences, and would get all cut up and scraped.  I would just go home and wash off with some soap and water.  The only time I was in a hospital was when I got hit in the eye with a stick, but still didn't want to go as I was fine, but my mom freaked. 
 
I eat rare hamburgers, steaks, and put them back on the same plate as the raw food when they came off the grill.   
 
I walked home from school alone, and stayed home alone until my parents got back from work.  When I went into 7th grade I took the subway to and from school on my own.  Even walked through some back allays some days. 
 
I remember going into bars with my dad and uncle, and sitting at the bar with my coke. 
 
I started driving before I legally could, and drinking before that. 
 
I played with knives, guns, and fireworks.  I cut myself, burned myself, bt am still alive to tell about it.  I even used some cigarettes to light off fireworks with my parents around, and nobody worried that I was smoking, because I wasn't.  
 
My first job, at aroud 16 or so, was doing landscaping for a company.  I worked with all sorts of machines, chainsaws even, and would come home cut, bruised, and filthy.  Nobody worried about it, or said I was in any danger.  I was just doing a crummy job until I graduate college. 
 
I am sure there are more, but these are off the top of my head.  It is amazing how quickly things change sometimes.
