About the travelling time to and from work, i would count it as part of work since it is a consideration you have to make. I would rather take just 30 minutes to get to work rather than 60 minutes. That is 30 minutes that you could be doing something more productive (i don't want to nap, watch dramas or play computer games on the bus or mtr!) and it adds up - over 200 extra hours a year.
About the long tunnel in the MTR stations. For most of the year when it is really hot or humid or wet, i would rather walk indoors in the tunnel than outdoors. Its like 5 - 10 minutes to get somewhere. It's not the end of the world.
