Problem is, there is no good way for long way travel but airplane or car. Flights become ridiculous expensive (thanks to green movent too), and if you don't own car...

It becomes middle ages again: you live all you life in one city, you eat only local food ("we don't need oranges all year around" from other comment in this thread), you wash with cold water (to conserve energy), you wear thick, warm clothes even indoor at winter (same). Yes, you have antibiotics and, may be, good dentist, if you could afford it. Thank you.

I'm joking about middle ages, but as they say every joke contains some part of joke...
