Not much has changed in 30 years
compudog? In bodybuilding alone, look at how the physiques have changed... 1985 Mr. O: Lee Haney (5'11, 240) vs. Ronnie Coleman (5'11, 300lbs), not to mention the drugs that have come to scene. National level NPC physiques are on par the O contenders from 30 years ago..
Aside from that look at technology. The fact that I typed this from a portable hand-held phone/computer would've blown the mind of someone in 1985. People have jobs on the Internet, HDR, plastic surgeries beyond belief, etc, etc... **** is way different from 30 years ago, and **** will be way different in 2045, almost unimaginable I believe
Let us not forget about an 112%+ increase in inflation, almost totally different worlds.
