this is interesting. there are no "bigguns" in either of my parents families. my dad is 5'9 my mom a little shorter. I am 6' and was the athlete, my brother is 6'2 and could give a crap about sports. pissed me off man! two more inches and I coulda been a contender! ROFL
our height is.....weird.

my kids.......my wife has freaks of nature in her family. she is 6', her dad was 6'4, her two brothers are 6'2. she has uncles and cousins even taller. so I had some "high hopes" (pun intended) for my kids. worked out OK for my daughter. she is 6' and HATES it, yet she was quite the volleyball player. my son is pushing 6'2, not the 6'5 monster I'd hoped for....but he'll do! so my kids are the offspring of two 6 footers and on my wifes side there was hope of super tallness....didn't really happen.

in the end....looking at family history....not a lot of it makes sense in my group.

There is something that I haven't seen mentioned. The amount of hormones we ingest and the affects that has had on our bodies. Not to mention all of the steroid based medicines that are handed out like candy to children.
To me those two things play a pretty large role in the changes we see as well.
You all remember what girls looked like when you were in school. I guarantee you it is not how they look today.

amen to that brutha!
I'd go to my daughters high school volleyball games and you just cannot tell what it is you are looking at.
is that a woman or a student?
is that a coach or a player?
