review my office

About six year i have worked in this office, now i feel tired. But when i got a called to interview, i wil compare the distance between my home and my office. Actually distance my home from my office is about 6 km, or about 15 minutes. Many friends said "How lucky you, your office is near from your home", I just told "Alhamdulillah, thanks God".
I calculate if i worked at Jakarta, how many hours i must spend out in the crowd of cars, in the polution air, and the smoke of the cars..
