Have a buddy with 3 sons. One was obsessed with sports, worked so hard to get strong, to work on his craft, so competitive, but ended up being only 5'8" and despite his best efforts he couldn't bulk up. The other 2 a passing interest in sports, but given much better size and athleticism, but not the love or work ethic for it.

Every time I talk to somebody that is like 6'8", but they have never touched a basketball in their life, I shake my head in disgust. I am only 5'10" and would have loved to have more size and athleticism, but was never blessed with those gifts.
