Welcome to the old boys' club, Adz.
You will notice more nose hairs, less head hairs, a tendency to break wind while you are sleeping, a growing fondness for vintage automobiles and a slowly enlarging prostate gland.
Alas, I am closer to 40 than 30 so truly envious of Bloodline's youth.
When I turned 30 my sister and I stopped by a KFC in Amanzimtoti. When I got my order, I noticed that the napkins said 30th Birthday, and I thought this was all a setup by my sister. I gave the person behind the counter some knowing winks and nodded in acknowledgment of this fine stunt.
It was only when I got home and saw the inside of the napkins, that I realised it was KFC's 30th birthday, as explained in the fine print.
My sister laughed like anything, and I was called Colonel Saunders for weeks after that!
