I look at Stallone and while he looks good from a muscle mass POV, he also looks old.  No telling what all those chemicals are doing to his kidneys, something has to scrub that crap.  I just eat good food (I like my   
broccoli    hot but crispy 

 ) don't drink much and I have never smoked.  I work out regularly and at my age just set a PB on my leg press.  I don't look muscle heavy like Stallone, but the guys in the gym who do are mostly on chemicals.
