I am 36 have one little child and feel like I am missing a bit of the country because I don't have a car, even if I have made few trips by train.
Also, a lot of my decisions are now driving by whether it is a short walk distance from home or not. Public transport in Copenhagen is respectful but a bit slow in my opinion (I am from NY), specially if I want to go to the edge of the city or suburbs - which I might want when I decide to settle roots here and buy myself a home (prices in Copenhagen are all time high).
