In my spare time, I love to go those rectangular courts in park and play basketball with my friends
I see you are very observant of shapes, do you like rectangles particularly?
Well, the geometry of rectangles has provided many useful insights toward advances in engineering in ancient times
It's true, Gobekli tepe is proof of that for sure
Considering the fact that it is above sea level, makes it architectural design even more appealing
And of course - breathable for humans. Arguably the most crucial preference. 
Anyway, do you also enjoy playing basketball in your spare time?
It's great, I could never play professionally, but my family all love it too.
Compared to college soccer, basketball competitions such NCAA are far better and has more audience
Yeah I would argue Basketball and UFC are the highest money grossing sports in America at least.
