There's a generation of super-giants incoming
Let me tell you what. I'm 28 now, and when I think about my high school class, most guys were around 5'7" or 5'8" at 18 years old. My height didn't stand out THAT much. Then I started university and it was similar. There was one huge guy in our class, but most dudes were only very slightly taller than me (and I was like 5'4" back then).
But now? Holy shit. I went back to uni because I had to do some tutoring and every guy was like 6'0" at the very least. Even the girls seem like they're 5'8" on average. Maybe even 5'9". I felt like a hobbit visiting the Netherlands. It was nothing like 2015.
What happened in the early 2000s? I swear to God. I am deeply convinced there must have been a secret program that every kid born after like 2003 must have gotten ultra high-dose HGH. Otherwise I can't explain this.
