Modern technology has made travel easier than it ever has been. I can buy an airline ticket today and be in Australia by tomorrow. When I was interviewed for a job in Germany I boarded an aeroplane in my native Britain, flew to Berlin, spent several hours with the team I would be working with, and then flew back home again, all in a single day. Before I made this trip I had several initial interviews remotely via Skype. When I was offered employment I gave serious consideration to working here, staying here during the the week, and then flying back to the UK for the weekend, such is the ease of travel that being able to cross several hundred miles and a few countries every week is simple and easy.
