Honestly your house is on fire, your kids inside, wouldn't you want someone who has the strength and endurance to save that child? Or say, ahhhh, we gotta fire you because you used steroids and send the fat guy in instead who dies right beside the kid! I've beat the shit outta my body for 20 years doing this job, and it takes a toll on everything, injuries etc. you get so wore down you start to let yourself go because of the constant pain and strain from the shift, now I'm in the best shape I've been in since I was a teen in the military, if I could is hand out pins to my coworkers, because I know this shit works! Why not chemically enhance your workforce to be stronger and more productive, oh wait, it would affect the sales of legal pain pills and the big drug companies and politicians would loose money! Silly Me
