An era long lost. Myself in 1989 at University.
At 179cm I was only 79 kg and very thin.
Even through I was thin, the height / weight tables you saw in high school physical education textbooks said I was overweight!
Now 17 years later I am overweight but I hope to lose that excess weight like I have lost my hair 
The worse thing is in October 2004 I was 10 kilograms lighter then I am now. But I hurt my ankle and stopped exercising. What a difference that makes.
You don’t appreciate your health until you lose it. Fortunally I am well on the way to overcoming my ankle injury, but it is still with me now as a minnor irritant.
You look pretty buff there, buddy!
