Once, I was having tea with a former secondary school classmate in the NUS canteen. He was then a student in the Faculty of Architecture and had a flair for drawing and the arts.

"Do you know what is the most beautiful curve in the world ???" He asked.

"What the heck curve are you talking about???" I had no idea what he is getting at...

"It is the inflection curve. You know... a curve with opposite change in curvature." He motioned with his finger and tried to draw an imaginery curve on the table top as he continued. "Like a letter 'S' that is stretched out loh..."

"But then why is it so beautiful???" I asked, with my curiosity-driven mind at work.

"Ai yo... you just born yesterday or what??? Are you a guy or not??? Look around lah.... Mother Nature has put inflection curves on women's body for us to look at.....

You see... from the small tight waist to the hips... from her back to her cute bottom.... and then.....

from her front bosom to her flat tummy... So it must be the most beautiful curve in the world lah." Gesturing with his hand and drawing many Ss in the air.

"Can't argue on that, Bro" I answered as I tried to sip my tea while glancing over the rim of my cup at the ladies. I put down my cup and added.... "When we want to say a woman is sexy, curvy and voluptuous, we always make the hour-glass gesture right???" This time it is my turn to draw two double Ss in the air with both hands. 

"That's right brother... you are catching on" He remarked. Then he fell silent as if in thought....

"If buildings have inflection curves..... think it will be damn sexy man !!!...."
