You don't run around school blocks to attend classes again, you aren't pressured to play ball on the field or follow friends to the gym. You now start sitting behind desk for hours, eating junks because you don't have time and you can now afford them. The only thing you do to pass time is to start drinking after work.
As a result your tommy is now protruding, you are now forming Man and feeling old.
I was at an interhouse sport yesterday, I couldn't run a hundred meters before I got a serious muscle cramb in my right thigh...I envy those young lads

You can still go to the gym after work and weekends tho. Its a matter of lifestyle.

Not all Jobs permits you time after work hours coz of late closure. Yea..., you could actually gym on weekends, I do push ups and abdominal before going to work then gym when I have the time.
